im one of six children (there's 10 years between me and my youngest sister) and we went away to one of the resorts down in southern WA in an off season. They generally have deals (like "Buy 2 nights, get one free" etc) and they generally have self contained apartments. Like where we used to stay, it was a 3 brm unit, but the upstairs was a loft that had 6 beds in it! the complex we stayed in had about 12 units, and we had our own pool and tennis courts that none of the other resort guests could use. It was still about $250 per night, but it was our special treat. just depends on how much you're lookin to spend.
