We have a block of rooms on hold at the Courtyard Marriott in Hyannis, MA as well as at the Radisson Hotel Hyannis. They are just down the street from each other. The rate is $239 per night, with a minimum of a two-night stay. Rate is valid July 24-29. These rooms will go very quickly, so reserve as soon as possible.

Flights

JetBlue and Airtran fly into Boston's Logan airport (BOS) and have very reasonable fares. Southwest flies into Providence's TF Green airport (PVD) and has discount fares. We have been told by some Cape natives that they find it easier to navigate their way from Providence and there can be slightly less traffic on this route, so that may sway your decision.

Cape Cod is equal driving distance from Boston and Providence, about 75 miles. There are only two bridges from which you can access the Cape; therefore, vacation traffic on the weekends can be heavy. Please allow for extra commuting time if you are arriving Friday evening or departing Sunday afternoon.
