Cape Cod has a very large number of accommodations ranging from basic motels to plush spa resorts. Resort areas include Chatham, Hyannis and Provincetown. Note that many hotels are only open seasonally April through October and that prices can increase dramatically during the summer high season and during festivals. Cape Cod is also home to several campgrounds. One of those is the Bourne Scenic Park. The Bourne Scenic Park is a campground located directly under the Bourne Bridge on the canal. It is a popular site that permits both tent camping and trailers. It is also right next to the canal with easy access to the bike trail.
The area along Route 6A in North Truro, just south of the Provincetown line is, for connoisseurs, the real Cape. This is "roughing it indoors" - the accommodations are not fancy - usually just one room, perhaps no kitchen or no drywall wall surfaces, and not very modern. For some, this is the real Cape--all the stuff south of the "elbow" is civilization. You have to go to Wellfleet, Truro or P-town to get beyond it.
Hyannis, is perhaps the Hub of Cape Cod. On the Main Street and the Waterfront you'll find Hyannis Harbor, the Village Green, the John F. Kennedy Hyannis Museum, the JFK Memorial Park, the Cape Cod Maritime Museum, waterfront restaurants, ferries to Nantucket and Martha's Vineyard.
