Destination spas can vary a great deal in the luxuries and amenities they offer, so there is a wide price range. Prices begin at around $200 per person, per night (double occupancy), including meals and some treatments, for more rustic destination spas, usually with a two-night minimum. A top-of-the-line spa like Canyon Ranch Lenox has a three-night minimum and can run $600 per person, per night (double occupancy) including meals and some treatments. And once you get there, you'll probably want more services and treatments than come with your allowance.

Always check to see what's included. Meals? Treatments? Tax? Service fees? And some resort spas even charge extra for yoga or aerobic classes

You can save by traveling off-season, planning your stay during the week rather than on weekends, and looking for special bring-a-friend programs. You can also make the most of your time by arriving early in the morning on your first day and leaving late your last day.
