If you call 407-939-2329 you can order things sent to the room or a table while you dine. Also, if you do a dinner show, let them know you want a candle on the dessert. We did that about two years ago and our whole area sang happy birthday to my son!
OMG these are great! We asked if our son could have a tour at the Animal Kingdom (Of the resort) and they gave us one (even before I became a Disney travel Planner). That is my best secret . We ask for tours all the time now, if they have time, they will do one.
From personal experience, early is way better. Less crowds and weather is more stable. I just had a guest come back this weekend and said "April, never again!" they preferred early May too. I already started on May of 2016 for her!
OMG - Food and wine time --- SO MUCH FUN!! If you choose that, go to Epcot during the week because it's less crowed. I book more guests for that time of year than any other! Plus so many more discounts come out for Set than summer! Locals come fri- sun ... Hope that helps.
