We did this as well and it was super easy and entertaining. Our bus driver was hilarious! Downside was we didn't get there till about 10 and they had us come back to the bus at 5:30. If this is your first time going, I would recommend it, just make sure you plan your day well and prioritize the things you want to do.
It was about the same for Seaworld. I felt too rushed at Seaworld though as the shows are the main attractions there and they are time consuming. We did not get to do everything we wanted and I was leaving disappointed.
