That's an impossible question to answer without a lot more info.
How many in your party? How many adults and kids?
What type of accomodations are you looking for? Regular hotel room, suite, condo, home.
Will you have a car or will you be depending on hotel shuttles (which I don't recommend).
What type of amenities are important to you?
How much are you looking to spend per nite?
As a very general answer to your question, IMO the best place to stay offsite is in a rental condo or pool home. You can get a 2-bedroom, 2-bath condo starting under $40/nite and a 3-bedroom pool home for under $100/nite. You get multiple rooms, full kitchen, and all the comforts of home and then some. Its a great way to vacation.
Give us more info and we'll be happy to make some more specific recommendations.
