I really enjoyed the fiesta. It was probably one of my favorite nights at the resort. The food is good. It is buffet style. So they had fresh salsa, guacomole, meat being cooked right in front of you, a carving station, dessert table (with churros, fruit, etc.). It was nice, a good selection. I would say that I wasn't wowed by the entertainment. They tried to get audience interaction but it seemed like people were coming to eat, staying for awhile and then leaving. For the hour or so we were there, they had a man walking around making balloons (that was actually really entertaining what he came up with), dancers, and a comedian. I would say it is worth checking out but I would probably go with doing dinner at Oceana (more intimate feel) and then maybe heading over to the Mexican Fiesta afterwards. Hope that helps!
