If you go to Orlando the last week in Feb/first week in March (if Easter is not early this year...I don't know when it is!), you will have no crowds, and the hotels will be rock bottom. We did it last year, it was sooo nice. No beaches, though, unless you drive to either the east or west coast of the state. Oh, and Disneyworld is anything but cheap, LOL.
Or you can come to Port Charlotte/Englewood/Venice area, (FL) on the west coast, and enjoy white sand beaches..... don't know about hotel prices, though I do live in Port Charlotte....
