I may have goofed! I think it is on the South side... There is another house called The Palm house that also looked nice with a pool as well and I believe close to town. You could always rent Jerry Jeff Walker's house for $5000 for the week. I think it will sleep up to 10 people.
I know that the Victoria House has a 2 bedroom Villa on the site. We were looking into doing the house thing as well but our plans changed. That was all I was able to find out as far as houses when we were looking. Have you checked on Casa Tortuga?
