I will be at Disney May 16-23 and we have already made dining reservations for the California Grill and we were wanting to eat at the Rainforest Cafe, which one is better, Downtown Disney or Animal Kingdom? I have not been to either so I am not sure if there is a difference. Also, do we need advanced reservations to eat at Rainforest Cafe or is it a walk in type of a place? Thank you! We are really looking forward to our trip, we're trying to get as much info as possible! Thanks!
