If you don't mind noisy and your kids loved the Rain Forest and they love Dinos, then you will LOVE TRex.

We go every other trip - not for the food..it is "meh" at best and waaaay overpriced... but our kids LOVE anything and everything dino-themed..so Trex is great for them. They have a HUGE gift shop (shocking I know

) and a really fun area outside with sand that the kids can dig for dino bones (like the Boneyard in AK but much smaller).
Before you go, check the internet for Landry's coupons. We were able to find a $10 of a $25 coupon and a .99 kids meal coupon.
