I'm having a young family visit from England next August. As they're flying in/out of Boston, we're looking to New England for a week of beach holiday. I'm thinking of Marriott properties vs. house rentals, but need something near the ocean that can accommodate 6 people in 1-2 rooms. I'd like to use Marriott points, but it appears that booking a suite with points can be problematic.
I'm thinking of Plymouth, Eastham (Cape Cod), or Newport, RI.
Does anyone have experience or recommendations? I'm looking for a nice beach, quaint town, things to do, but not too overly touristy. Any out of the way places - Marriott or not along the coast?
