We went last fall and had quite a good time. The architecture, landscaping, etc. are a notch above what we're used to in the U.S. "Magic Kingdoms". Unfortunately the janitorial services, maintenance and upkeep, and fellow guest politness are not. Cast member courtesy and service is up to the usual high Disney standard.
My #1 recommendation is to absolutely make sure you ride BTMRR. It was the best coaster in both parks, and definitely world-class. SM was a letdown (too bumpy--we all got headaches and my wife even lost an earring!), RnRC was a letdown (same basic ride but the pre-show was gone and the decor cut-rate), although I have to admit Crush's Coaster was a real hoot.
My eight year-old daughter's favorite thing to do was Alice's Labyrinth, a cool little hedge maze at the edge of Fantasyland. I think she liked the novelty of it, but she continually reminded us that she wished they would put one in at DL.
Finally, you really do need dining reservations if you want any of the sit-down places in the parks. We didn't have them and tried several times to walk-in to Walt's, etc. and were never successful. That being said, the counter service places were universally good and reasonably-priced.
Buffalo Bill's Wild West Show was a fun way to spend an evening. It's definitely unique, and although there were hints of Hoop-De-Doo in it, it was more like an old-fashioned rodeo than a comedy show. The entire show is done in English, which was nice!
