I have allergies to milk, peanuts, lemon, watermelon, and pears what to eat at theme park, what do you recommend?

See allergist: It is unusual to be allergic to so many food items with totally different structures. You need to consult an allergist to first find out if you are indeed allergic before you can deal with your "allergies" effectively. In the meanwhile, ask questions in restaurants and read labels.

Workup/Mgt: Multiple allergies to foods can occur, but the diagnosis should be verified by careful history and lab testing. I would recommend an Epi Pen that is carried with you if you have allergic reactions to foods. I would also suggest avoiding public shared water fountains and handles, since these may become contaminated with food allergens.
