Hi Sheralyn,
Four days, four theme parks...I think one park per day is a great idea! You could certainly spend an entire day in each of the four Walt Disney World theme parks, so I think you would be more than satisfied with the base ticket (one park per day). I think you may be a little crunched for time if you tried to include a water park visit, those really deserve a day to themselves as well.
You'll be happy to hear that special dietary needs, including allergies, can be accommodated at most table service restaurants throughout Walt Disney World. Due to your daughters allergies, I suggest selecting table service restaurants at each of the theme parks you will be visiting and make your dining reservations as soon as possible. This can be done by calling 407-939-3463, and be sure to mention the allergies at the time of booking, or soon thereafter by emailing
specialdiets@disneyworld.com and reference your dining confirmation numbers.
I would start
here for researching and selecting table service restaurants that will appeal to your entire party.
Have a great trip!
