Oh how I wish you had twice that many days to spend with Mickey but I am excited you will be able to go at all! Your fiance will see so many changes that it will be like his first time all over again.
A trip to Walt Disney World
must include time at the Magic Kingdom. I would set aside one day for this park and be sure to get some
dining reservations in place. The day and evening parades are wonderful as well as the fabulous fireworks at night. There is just something about the "magic" of the Magic Kingdom!
EPCOT would be another good choice for a day in the parks and again get some dining reservations for one of the World Showcase restaurants. Illuminations is the fireworks show in EPCOT and absolutely my favorite so don't miss that. It is nightly at 9 p.m. except some Fridays at 8 p.m.
It is possible to take a water taxi from the International Gateway entrance of EPCOT to the Hollywood Studios. If you want to take a break from EPCOT this is a nice way to see yet another park but if you are having fun just relax and enjoy yourselves and don't try to squeeze everything in. With only a half day left you can either try to see some of Animal Kingdom or Disney's Hollywood Studios or explore Disney's Downtown Marketplace.
Visit
www.disneyworld.com and study the attractions at the parks you decide to visit and go with a basic plan. You will not be able to begin to see and do everything in such a short time but enjoy the magic that is there and I am sure you will be planning a return trip soon.
