Just wanted to say thanks for all the advice ladies.
We ended up only doing two days at Seaworld (One morning/afternoon and one afternoon/evening), one day on the river walk/Alamo and then to Houston for a day at the Houston Space Center. The babies were well behaved and everyone had a great vacation.
Ashton loved the animals. He even liked getting splashed by Shamu...Adriana did not like that part at all.
We used our BOB stroller for the first time and LOVE IT!!!!
Can't wait for our next family vacation.
