One thing that Disney needs to really look at when they do the Tropical Americas replacement for Dinoland is putting in a standard 1 TS dining option in there. As it stand Y&Y kind of has the monopoly inside the park I believe. The Rainforest cafe is at the front/outside of the park, but that is aimed at young children. Tusker house, which is a character dining buffet, so also aimed more for children, this is WDW after all so thats fine. Tusker House has interesting food but also being a buffet turns some people off. Tiffins is there but that's a signature dining so is more expensive and would cost 2 TS meals if on the
DDP. Y&Y is really the only 1 TS meal non-buffet meal inside the park.
