You're gonna have a great time at Disneyland!
I agree with the consensus of the thread... 4-6 days and you would not be bored... dining plan is a weird ripoff...
If you would normally stay at a Value or a Mod at WDW, stay off-site at DLR.
If you would normally stay at a Deluxe at WDW, stay at the Disneyland Hotel.
If you would normally stay at the Grand Floridian, stay at the Grand Californian.
That's a very, very basic guideline based on the rough way the prices line up, but it's not really black and white. Staying offsite at WDW normally means you're miles away from the parks and fighting traffic on 192. There are many nice hotels offsite at DLR that are within walking distance of both parks. Even if you stay at deluxes at WDW, it would still be worthwhile to look at the fancier offsite hotels... everything is really really close. There are many well-reviewed hotels that are closer to Disneyland AND DCA AND Downtown Disney than the Contemporary is to Magic Kingdom. Looking for my dates in November, admittedly during a slow season, I found lots and lots of places around $110 per night with various discounts to bring the price further down. Here is the link to the
Wikimapia map I use to look for hotels.
Also, because of the local crowd patterns, there is a noticeable difference between Monday-Thursday versus Friday-Sunday. I've never really noticed crowds vary by the day of the week at WDW, but it's very noticeable at Disneyland. I would really try to hit as many Monday-Thursday days as you can.
