How large is your pary and what are the ages of the people in your party?
Here are some ideas:
Adult Only
-- Dinner at Jiko at the Animal Kingdom Lodge (signature dining I haven't tried yet, I'd love to do this with DH // think he'd love it // not worth it to go with picky kids, though, for me)
-- If you're a foodie and don't mind spending beaucoup bucks on a unique dining experience and don't mind dressing up a bit, I have heard rave reviews about Victoria and Alberts at the Grand Floridian (Disney's only five star resturant). It wouldn't be worth it to me, but I'm guessing DH would absolutely love this.
-- I'd like to try the Titanic dinner theatre experience on I-drive too (a retirement party for Captain Smith) // I've heard great reviews regarding both entertainment and food.
All in Party are Age 16+
-- I'd love to try the "Key to the Kingdom tour" (requires admission to the MK too). Must be 16+ to participate. We plan to go on our next trip (DS turns 16 at the end of August). Cost is somewhere around $60 pp plus you need MK admission. // This tour gets rave reviews, and I've always wanted to see the utilidors (staff area that MK is built above), and you do see them briefly on this one. The tour lasts about four hours, I believe, and includes lunch.
Excellent permanent shows in the Orlando area (picks for adults only and/or families with tweens/teens (I wouldn't be as inclined to do these with young children, but some families do)
-- La Nouba (Cirque de Soliel) at downtown Disney
-- Blue Man Group at Universal City Walk
These are excellent shows, and each is in a permanent/custom venue. These are bargain yet the same quality compared to similar shows in Las Vegas. If you have any interest in doing these and haven't been to a similar show before, Orlando is the best place to do these from a quality/economic stand point.
A unique dinner break / sit down table meal for an MK day (good for the whole family)
-- Ohana at the Polynesian hotel for dinner. Even kids like coming here (very family friendly, and I thought the food was excellent). Not truly a foodie place, but foodies would like it too I'm guessing. I think the food and atmosphere would appeal to most people. Price is $35 or so pp for anyone age 11+ // younger children are less. Visit the grounds and walk around a little after dinner too.
Family with little kids who like the Disney Characters
-- Do a character breakfast or dinner (I don't have recommendations because my son was never interested in this. When younger he was scared of the character. When no longer scared the character they really didn't interest him // only as a teen has he ever stood in line to meet any) My brother and his family did this once every trip when his children were younger, and they loved it.) // Ask specifically for recommendations in another post if this is of interest.
