We just stayed at the Rosen Plaza; about 2 miles from Seaworld. We got it on Expedia for $55 a night, I think their rates would normally run well over $100 if you called their hotel. Large pool, clean rooms, room service, etc. Sometimes you can find motels at roomsaver.com and some of the motels will take reservations with the coupon, others it is at checkin only. I know someone who got a BestWestern room for 35 a night on International Drive.
