I
do advise staying on property, which if you are staying at a value than you are.
Know what a Fast Pass is and how to use it.
Take advantage of morning EMH's (Extra Magic Hours offered to Disney resort guests only). You can usually get a lot done in that park in the extra hour before the park officially opens to everyone else. Visit the Walt Disney World website, see what attractions you and your family would like and schedule those as your priorities and anything else you do is a bonus.
I highly recommend watching all nighttime shows: Illuminations at EPCOT, Fantasmic! at Disney's Hollywood Studios, and Wishes at the Magic Kingdom.
You are going at a busy time of the year, be prepared to stake out a spot for a parade or a nighttime show early and don't expect to walk up 10-15 minutes before and grab a good spot - unless you are
extremely lucky.
If your not on the Dining Plan, I recommend that you make ADR's for a couple of restaurants anyways just for the experience. Visit the restaurant boards for reviews of different places. Be certain that you make ADR's for any sit-down restaurants - you can begin booking 180 out. Some people are lucky and happy with getting what they want without the ADR's -
most people aren't so lucky. So, if there is any place special that you and your family want to eat at, I'd make a ADR as 99.9% of the time you will not be able to get into a restaurant as a walk-up.
Read up on the theme park pages to learn anything from the fact that Disney does not allow Heely’s in the parks to great spots to camp out for Illuminations and over looked stuff that not everyone pays attention to – such as the Streetmosphere actors at Disney’s Hollywood Studios. (A group of improve actors pretending to live in 1940’s Hollywood and they are hysterical). Just read up on the DIS and you will learn a lot of information.
But most important: Just have fun. It might be crowded while you are there and you might not get to see it all your fist time (because there is soooo much to do there) but just enjoy the sights and what you get to do and the food …. Just don’t forget to stop and smell the roses. In my opinion, there’s no place like Disney.
