Where did you find the operating hours at for Rainforest? I wasn't able to find them and I agree that TRex will probably mimic operating hours like that of its cousin Rainforest.
Reason I ask is because my plane lands late in the day. I'll need somewhere to eat when we get in and I am dying to see TRex but won't be able to make it to TRex until 10:30ish on a Saturday.
I hope I can make it in time to get a nibble and drink from there.
