Gayla,
Your best bet is to use the Lake Links section of this site. You can get to the lodging section by clicking here.

I've stayed at the Margate, Misty Harbor, NASWA and Shalimar Inn. I think they are all ok but don't expect the Ritz. Also search the archives for info on specific places, there are people who don't like some of the places I mentioned. I'd book soon if I were you, that's a busy week.
Good Luck
