I've eaten at TONS with friends and family, and my DH and I have been to MANY and we don't have kids yet! We've done CM (Chef Mickey's) for breakfast on our anniversary and LOVED it! CP (Crystal Palace) for breakfast and LOVED it, Akershus for breakfast and that was declared by my DH as his fav fooodwise

, eaten at LTT (Liberty Tree Tavern) twice and that was MY FAV (it's too bad they don't have it as a character meal right now or we'd be eating there in Dec). Hmm let's see...OH we also LOVED Garden Grill! LOL we always seem to enjoy eating with the characters! The only one that I wasn't as impressed with was CRT (for breakfast). We ate there about 3 years ago because I begged to eat in the castle, and it was ok. Food wasn't special, princesses were very rushed, but I did LOVE the view we had of Fantasyland! For our upcoming trip in Dec we have ADRs for several character meals:
1900 Park Fare (for dinner)- I've eaten here for breakfast twice. Once with a friend and once with my sis and the food at breakfast was WONDERFUL! The characters are great too! I wanted to eat with Cinderella and her stepmother and stepsisters this time.
CP (for dinner)- As mentioned earlier, DH and I ate here for breakfast and really liked it. I love the Pooh characters!
Cape May (breakfast)- My sis and I ate here during spring break and we really liked it! The characters were GREAT and it seemed somewhat less hectic than some of the other character meals. Also I really liked the bread pudding
Donald's Safari Breakfast- This will be a first for us.
So as you can see we're not afraid of being a party of just adults lol. Hope you have fun with whatever you decide!
