Hi, Judy! It really all can be overwhelming. There is so much to see and do at Walt Disney World that you can easily become flustered over everything! Fear not, that's why we're here!
I will tell you honestly that the closer you get to your vacation, the more difficult it is to book your dining reservations. You won't need them for every meal, and there are a number of really good meal choices without needing a reservation at the many counter service locations, but if you head on over
HERE you can browse the list of Walt Disney World restaurants, and you can book online for most of the meals you might want. I've had good luck at the last minute with Restaurant Marrakesh at EPCOT, the Wave at the Contemporary Resort, and even sometimes at the Crystal Palace and the Garden Grill.
As for what to do, again, the best site is the
www.disneyworld.com website, which will go through things that you might need to know. Click on the top where it says Discover, and you can see an overview of all of the theme parks, water parks, and more. I like to tell people to go to each theme park description and come up with a list of things you think you'd like to do. If you have time, plan one day at each park, and do your must do items, then fill in from there.
Take your time, have fun, and try not to get too overwhelmed! We're here when you need us!
