We just stayed at Hilton Grand Vacations Suites at SeaWorld in a 1-bedroom suite in that price range that has a fantastic pool area. 2 pools and at least 4 hot tubs. We had a hard time dragging our 6 year old away to go do anything once he got to that pool. The room was great. We are nearly certain we will stay there again on our next trip.
It sits just across the street from Sea World and was only a 3 minute drive to the entrance and parking lot. You can walk it, but my wife convinced me the $12 parking was worth it since you're going to be doing a good deal of walking in the park anyhow.
Nice thing is you only have to pay parking once a day. You can get there early in the morning, head back to room for lunch (our room had a full kitchen.) and a break, then head back to the park for the evening shows and fireworks. Quick note, you can also see the fireworks from the pool area, but above a tree line, but seeing fireworks from the pool area only increased my sons love for that area. Also, your parking is good for Aquatica as well. We started one day there and did an evening at SeaWorld and just had to present our receipt from Aquatica.
Hope that helps some.
The i-ride also stops right outside so it was really great!
