Well… I don’t know if it’s a good way but this was my strategy for MK yesterday and Wednesday:
Book first ride at 7 am: On Wednesday, it was Mermaid. Yesterday, it was Jungle Cruise.
I effectively used Mermaid as a “burner” ride because as soon as it’s used, the system allows you to start getting other ones. Otherwise, you have to wait 2 freaking hours before being able to make another. Which is stupid. Because after you use that first one, you can just refresh the heck out of the app and pick up rides at times you prefer. I wasn’t going to wait and watch all those good/better times go by. And I knew if I wanted to re-ride Mermaid later in the day, that thing’s wait is never that bad.
JC was my hardest ride to get on Wednesday and so, for yesterday, I said well, I’ll try to pick up that first, otherwise I won’t worry about it and probably pick up a time later in the day like we did on Wednesday when we road it at 430ish. (I also don’t love JC that much so it was still a bit of a burner in my mind).
That being said, I picked JC up for 930… arrived at 925 (cause there’s still a five minute grace period prior to your technical start time) and wa laa, off we went. Soon as you go through the two LL stands in each ride, you can try for the next.
I ended up “saving” some GP+ rides for later in the day because standby waits were low until around 11. So we were able to ride HM, BT, Pirates, Pan, among others, between 4-9 with no problem after riding them standby in the am.
We wound up criss crossing the park a little bit but MK is a small park so it was no big deal.
We GP+ed 10 rides yesterday strategically, waited no more than 20-30 minutes for any one thing, and rode quite a few rides twice.
(Full disclosure, we had early entry as resort guests (Mine Train, Pan, HM were our rope drop rides), and did have Mine Train and Space Mountain purchased for later in the day too.)
(Full disclosure #2, you have to be willing to aggressively refresh. I was not on my phone the whole day but there were short 5-10 minute bursts of phone use before I’d get what I wanted when I wanted it. Sometimes I was looking at convenient times for multiple rides. People are always dropping their time slots, even for things like Pan. It felt very much like FP+ in that respect.)
EDIT:
For Epcot, honestly, with the exception of TT, you don’t really need GP+. We used it but it was much more casual as most of the rides had minimal waits. Think we ended up with TT around 11. The GP+ didn’t book that fast. I picked up a Soarin’ around 2 with ease. We rope dropped and rode Frozen twice, did a paid LL of Remy, did all of Future World, and by that time, it was time to enter the VQ for Remy (you can do VQ and paid LL on the same day to ride it twice).
For AK, similar to Epcot in that I didn’t feel I absolutely needed GP+ but it helped cut waits a bit. We rope dropped FOP and also had a paid LL for later. No one should ever purchase Everest… just do single rider if you wanna get on quick. Shot around and did all the rides including Safari twice, did use GP+ on the (sadly Covid modified) Festival of the Lion King, out of the park by 230.
For DHS, it was the only place I felt I had to have strategy again. If you can pick up an early time for Slinky, do it, as GP+ go fast! I could not get it early the first day and so hoped to pick it up later (I was indeed successful. Thanks refresh! On Day 2 at DHS, I had a free GP+ Slinky Dog from Guest Services due to MDE shenanigans, so that was a load off. And I never feel a desperate need to ride it twice).
Rope dropped ROTR, also paid for an LL later in the day. MMRR doesn’t really need to be paid for, line moves faster than the wait says. TSM was my “burner” both days we started at DHS. (Though I love the ride, there’s just less to GP+ in DHS). Picked up TOT, Rockin’, Smuggler’s as able. TOT was hardest to get but that’s mainly because one side is down right now or at least was the past week. Didn’t GP+ any of the shows. No reason to.
Any questions, just DM me. Happy to explain in more detail but I’m sure people don’t want to read any more of this novel.
EDIT #2: Just to clarify on the waiting 2 hours thing. It’s not 2 hours from when you made your first reservation at 7 am… it’s 2 hours from when the park first opens. So if MK opened at 9, then your next window wouldn’t open until 11, 4 hours after making your first reservation at 7 am. So picking Pan at 1230 is dumb for your first GP+ of the day. Try for it later after using GP+ on some other things. That’s why I found it so aggravating and developed the burner strategy.
