I don't know why I haven't replied to Cyd's post earlier BUT...in reading the comments...I have to make one major recommendation. Call Disney Dining (I think the number is 1-407-WDW-DINE) and book Rose & Crown at EPCOT at about 7pm for your Friday, May 18th dinner. Get there about 15-20 minutes before your reservation and check-in asking for a table on the outside patio facing the water. Have a long, leisurely dinner...and watch the very enjoyable "Illuminations: Reflections of Earth" from there. We always do this at least once during our trips. This is not only the best nighttime entertainment show that WDW has to offer but it also embodies the original spirit of EPCOT. EPCOT is open late Friday night and usually clears out after Illuminations so you should have plenty of play time until midnight that night.

Plus, on Saturday (even though you didn't mention it) make sure to see Spectromagic at the MK at 9:00pm before Wishes at 10:00pm. If you get there "late" for the parade, go over near the Pecos Bill Cafe in Frontierland (end of the parade route), it's always the last area to fill with people and you can almost always find somewhere to sit.

And, as commented to Cyd's post, when at Pleasure Island spend as much time as you can in the Adventurer's Club. It's comedy-improv dinner theatre without the dinner! Many different "shows" in the various rooms and the library theatre leading up to the hilarious "Hoopla" closing show.

Have fun and congratulations!!! If you need anything else, let us know.
