I am looking for a place thats clean,affortable,lots of things to do and kinda close to Sea World or the airport.

Best hotels like the radisson may not be affordable but its sure clean and fancy.

Try Studio plus or Extended Stay America
They have lots of room and little Kitchens.

If there are more than two of you going its far better to rent a villa. Check out this link.
