If you are a family or a group of friends and you don't want to be cramming yourself into some small space, pushing your gear into the corner, and finding a few square inches to lay your head, check these photos out: full-size kitchens, airy bedrooms, deck space and lounge areas, room enough for all. Rates start at $85 per night for the off-season, $115 for peak season. Book early and indulge. You owe it to yourself to run for the oceanside.   Better this type of setup after a day of driving than the cramped interior of a small tent. We are of the belief that "away from home" need not mean away from comfort.
