Our DDs (ages 6 and 9) absolutely LOVE GK and insist we book it on each trip. Last time we went, we were with 2 other families, all with DDs ranging in ages from 1 to 13.
All had a great time dancing to the macarena with Goofy, and meeting a wide variety of Disney characters. I believe that most of the princesses were there, as well as Alice in Wonderland, Captain Hook, Mickey, Minnie, Pluto, Alladdin, Chip 'n Dale, etc. The food was also great for all the kids and adults. Such a fun dinner that every one of us have fond memories of during our trip.
