In June, a bus company is taking a trip to Cape Cod and is including a trip to Nantucket Island. They will have a guide to take us around the Island and then people can do things on their own. My question is - can I walk to the lighthouse(s) easily? Can I rent a bike or moped on the island to get to the lighthouse(s)? I have been to Cape Cod but never to Nantucket so I was going to take this trip just to get to the island. What do you think?
