My wife, 9 year-old and I visited the Nantucket Hotel for the first time for a few days before Christmas and liked it so much that we returned the next week with some friends! We have visited the sister property on Martha's Vineyard (Winnetu) many times, and found that the Nantucket has all the same features--great location, friendly staff, large cozy rooms (w/kitchenettes), lots of kid activities. Special thanks to Jamie, the general manager, who took us on a Nantucket tour on the hotel's 1930s school bus, to Tim and Nicole at the front desk, Dmitri at the Breeze, the hotel's fine restaurant, and Hugh, our arrival shuttle driver whom we ran into on the ferry back to Hyannis transporting a sick seal to the mainland for treatment. Even wildlife gets personalized service from the Nantucket!
My only suggestion for improvement is that after looking at some pictures of my son and his friend playing chess in the library, I noticed that the board needs to be rotated 90 degrees so that the bottom right corner is white for each player. :)
