Favorite WDW Vacation Planning Resources
https://disneyworld.disney.go.com/ Here's the place to explore resorts and dining choices , sign up for a My Disney Experience account, plan your fastpass and dining experiences and order your magic bands. You can also order a Disney Vacation Planning video- https://www.disneyvacations.com/dv/en_US/VacationPlanningDVD/ The best book for planning your trip is The Unofficial Guide to Walt Disney World. They put out a new edition every year with all the updates for whatever changes have happened in the previous 12 months. Even though the book stays 90% the same from year to year, we still like to pick up a new copy yearly. You can get it from your local bookstore or Amazon- HERE. There is so much in this book, detailed info on every attraction and hotel and restaurant as well as my favorite- Touring Plans. The touring plans help you maximize what you see while minimizing the wait times. They also have a companion website- http://touringplans.com/ where you can view much of the same info and much more. The website has some open access and requires a subscription for full access. In my opinion the subscription is well worth the price for what you get! Online, http://allears.net/index.html is a great resource. Pictures and descriptions of everything at WDW plus all the menus and rehab and refurb schedules. A go to place for info on anything WDW related.
My other favorite is http://disboards.com/ . The Disboards website is a forum filled with WDW enthusiasts who share and swap information. If you are interested in the newest news and rumors or a strategy for getting from one resort to another for dinner or how to score a reservation at the hardest to get restaurants- this is the place to go! If you have a question, there are so many people willing to help you out and answer.
Pay attention to dates. You can start making Advance Dining Reservations 180 days in advance if you are staying on property and Fastpass+ choices 60 days in advance.
