The Block Island Chamber of Commerce is located at the Old Harbor Ferry Landing, inside the Welcome Center.

The Chamber staff keeps listings of last minute availability, so if you plan your overnight stay a bit late they will be able to help you find a room. 

While the Chamber does not actually book the rooms for you, they are aware of all the types of accommodations available on Block Island and can point you in the right direction, whether you are a party of 2 or 20.

The Chamber staff can be reached daily at 1-800-383-2474. 

They are a great resource to those planning a Block Island vacation.
