Replacing Hersheypark with Cedar Point is a MASSIVE upgrade! Well done.
CEDAR POINT GUIDE
Cedar Point comes close to perfection for me as a pure coaster park. If you go looking for theming you'll be disappointed, but if you want energetic atmosphere, an interesting setting, lots of jaw-dropping sights, great people-watching, and of course thrills galore, it is utterly top notch. Cedar Point is the Magic Kingdom of coaster parks. For coaster enthusiasts, it has that same "Mecca" status...and as a result it gets just as crowded. Heck, both parks share a dramatic arrival across a body of water. Cedar Point's perch out in the middle of Lake Erie overlooking Sandusky is something else.
Since you'll be doing Kings Island and Cedar Point back-to-back over several days, it might be worth getting a Cedar Fair Platinum Pass. This gives you unlimited chain-wide park access, plus free "extra ride time" access in the mornings (and sometimes the evenings). This will be especially useful for snagging quick rides on the high-demand headliners. Kings Island is a great stepping stone park as you work your way up to Cedar Point. You're following the same personal coaster journey I once trekked.
At Cedar Point, I wholly recommend rope dropping
Steel Vengeance, my #1 favorite coaster in the whole wide world! High demand and low capacity can mean long lines. SteVe is located one mile from the main entrance, so instead park out on the tip of the peninsula and enter Cedar Point through their "International Gateway" entrance near Frontier Town. (Near the water park.) SteVe will wow you with the world's record for airtime (around 30 cumulative seconds) and a nearly relentless prime ride time which never seems to end. It's RMC's masterpiece to date...though Iron Gwazi nips its heels.
If Steel Vengeance is most comparable to Iron Gwazi (my #3), then its next door neighbor
Maverick (my #6) is most comparable to Velocicoaster (my #4). This is the original Intamin "Blitz" launch coaster. The stats are unimpressive, it isn't intimidating, but the hyperactive low-to-the-ground layout will take your breath away. Great thrills in a tiny package.
Millennium Force is many enthusiasts' fave at the Point. It was the first coaster over 300'. Super intimidating the first time, then pure fun afterwards. Just an incredible first drop which will launch you from your seat, plus a ton of massive airtime hills throughout coupled with tremendous speeds. A true crowd pleaser! Do this after Maverick, unless instead your priority is -
Magnum XL-200, the first coaster over 200'. It's an Arrow Dynamics coaster from the 1980s, made before computer-assisted design, so it's showing its age, but it's still held in reverence by most enthusiasts as another airtime dynamo. The out-and-back layout's return trip especially offers unique triangle-shaped ejector hills. The third row from the front is the legendary "magic seat." Give it a shot! (Generally, though, front or back seat is the best on most coasters depending on your tastes.)
Top Thrill Dragster will probably be closed for you, it's likely neared the end of its service life.

If somehow it does open, do it immediately! (After SteVe and Maverick.) Lines can back up. TTD is a one-trick pony, but what a trick! Launch well over 100 mph, vertical climb well over 400', then a twisting vertical drop straight down. All in under 30 seconds. Kingda-Ka at SF Great Adventure is similar, and taller, but this is a superior ride experience (hooray for just lap bars!).
After you've done these rides above, you can visit the Midway towards the front of the park. This is where all the B&Ms and seagulls live. Since most guests enter from down here, these rides see longer lines early in the day, then crowds spread out later on, kinda like Spaceship Earth. These B&Ms include...
Raptor, a first-gen B&M invert. Built into a compact lot with lots of whippy transitions. It's extremely forceful, one I tend to ride defensively. Beloved by fans of positive-Gs. Watch out for that final brake run!
Gatekeeper is a graceful, majestic wing coaster which sails right over the main entrance. You'll ride to the left or side of the track - try both. While it looks extremely intimidating, the actual experience is more "Soarin' if it were a coaster." Beautiful, almost Zen. A front row ride comes closest to feeling like true flight, since there's
nothing in front of you, not even track.
Valravn is the world's tallest dive coaster, somewhere around 250' or so. It's psychologically intimidating, but a fairly middling actual ride experience. (I prefer SheiKra.) You'll be dangled vertically facing the earth before a chain untethers from the train and you enter freefall. The layout which follows is standard B&M.
Rougarou is a floorless coaster (basically a gimmicky sit down coaster) which used to be a standup coaster called Mantis. The track profiling is a little uncomfortable since it was originally designed for a higher rider heartline. Pretty textbook B&M looper. Still, you oughta try it.
Then there are Cedar Point's multitude of supporting coasters.
Gemini is a unique 1970s wood & steel hybrid racing coaster, with an intensity right on the edge between family ride and thrill ride. I vomited on it once!
Blue Streak near the front is the park's only true wooden coaster, dating to the 1960s, with a classic jittery boardwalk woodie feel.
Corkscrew, one of the first modern inverting coasters, is the park's least comfortable coaster; I do not recommend this one.
Cedar Point Mine Ride and
Iron Dragon both offer family thrills equivalent to Disney.
Woodstock Express is like Universal's Hippogriff, if you're collecting credits.
Among non-coaster rides, there are a few goodies. Most of these work best as relaxing cool-downs between the big beasts. The
Cedar Point & Lake Erie Railroad offers some unique views, genuinely useful transportation, plus the leg leaving Frontier Town goes through the indescribable camp masterpiece that is Boneville.
Cedar Point Downs near Valravn answers the question "What if a carousel were a thrill ride?" It's great! There's a
Sky Ride over the Midway for the views and the breeze.
Snake River Expedition was added last year for the 100th anniversary; while I haven't done it, I'm told it's like an Old West version of Jungle Cruise. Sounds interesting. If you're looking to truly relax, go for a stroll on the beach between Gatekeeper and the Breakers Hotel. (If you somehow need even more to do, there are like 50 flat rides.)
There are a few sit down restaurants which offer a nice respite from the adrenaline. I most highly recommend Melt, plus a BBQ place outside the park on the marina near the Valravn entrance (forget its name). While Cedar Point was improving their food offerings during my visits, it seems they're backsliding lately. Most of it remains basic carnival fast food. Do some research into this.
