August is the most popular month to vacation on Massachusetts' Cape Cod and consequently it's also the most pricey.  Which is why we were pleasantly surprised to see this deal come our way.  Two properties on the Cape (and one nearby in Plymouth) are serving up savings now through August 31 .  With the 40/40 Deal, stay two nights and get 40% off your third night, plus you’ll receive a $40 resort voucher good for on-site dining or spa services. If you’re looking for a two-night stay, you can save with the 30/30 Deal, which takes 30% off your second night, plus chips in a $30 voucher.

The deals are good at the Cape Codder Resort & Spa in Hyannis, Dan’l Webster Inn & Spa in Sandwich, and John Carver Inn & Spa in Plymouth.  The Cape Codder and John Carver are especially family-friendly, with waterparks (think indoor wave pool and 80-foot waterslide), evening bonfires, sing-a-longs and kids' programs packed with activities.  Nightly rates for a double room at the Cape Codder in August start at $199 for a double room, so the 40/40 deal will save you $120 on a three-night stay ($80 on the lodging tab plus $40 on dining). At the John Carver, rates start at $209 per night, so your savings would be slightly more.  Enter promo code RP4040 or RP3030 when booking online.
