They do have a shuttle to SeaWorld. You have to have a reservation to get past the security gate. Check-in is 4:00 pm and check-out is 11:00 am. However, they said you can arrive at 10 am and they will store your luggage until the room is ready so you can take advantage of the all-day activities. The same thing when checking out, you can check-out and they will store luggage until you leave so you can actually enjoy two days of the resort when only staying one night. They did away with the wristbands so as long as you are on premises you can participate in activities so if you end up with 5 people in a room, all 5 can use facilities.
They have a lazy river, small waterslide, movies and popcorn on the lawn at night, some complimentary and some additional expense activities (like making sock monkeys), hiking trails and bikes you can reserve to ride bikes on trails, golf course. They also provide the makings for smore's each evening.
