I am visiting New England at the end of March and would like to take a trip to Cape Cod from Boston. I believe that from Boston we would go to Provincetown (is this right?). I was then thinking of spending a night in Provincetown and a night in Hyannis (with the intention of then going to Martha's Vineyard). Is this too much/enough time to have a look round and make the most of this short trip?? Any advice would be much appreciated! thanks!
