E.P.
I love going to Disney! I have never stayed at the Wilderness but I have a friend who loves that location - don't know what room they would stay in but just knowing our personal family vacation, I would opt for the (semi) privacy. It is also very nice that you are staying on property and are able to take advantage of the early morning/late night extra hours that are only offered to guests on property. Just keep in mind, the time of year that you are going in could be (very) high time! With Easter falling on April 12th and the Greek Orthodox Easter on April 19th and the many Spring Breaks....weather-wise it's lovely but many crowds! Been there-done that! You're children will have a great time-remember to book your "princess" breakfast (Magic Kingdom/Castle) 60 days in advance, if you want that - and it REALLY is 60 days. At 6 am in IL you will need to start to call -for 60 days in advance. It will fill up in less than 30 minutes. The Crystal Palace (Magic Kingdom) is not as concerning -check on when they suggest you call - it's a character bkft and a wonderful one at that! Winnie the Pooh and friends are all there, plus some. Good way to get your autographs out of the way - without standing in line. (Yep...your kids will get sucked in to getting character autographs! It's fun for a while but then you find yourself standing in, yet, another line!) And, EPCOT is very cool! They have stuff for little kids, too. Kids start out making a mask and in every country they will be able to embellish it and you'll get the opportunity to enjoy EPCOT! Best advise....book a dinner at a restaurant in MGM who offers a FANTASMIC package. Easiest way to get good seats at Fantasmic without waiting in line or spending a ton for dinner. Have fun!
