For your budget, you can stay at a very nice Disney Resort. If your destination is Disney Parks, it doesn't get much better than to be on Disney Property, IMHO of course. You would have all your Transportation taken care of, to all the Parks as well as to and from the Airport. ( MCO) They all have wonderful Pools. You can even add Tickets and the Disney Dining Plan, one neat little package, no stress, no worry.
There is a nice Room Discount for stays til mid June, must be booked by Today however. Next Promotion for stays after June 15th should be announced once the current offer expires
