If you want to pick up any alcohol or snacks to keep in your hotel room, there is a liquor store in the Bermuda airport after you get through security. There is also a grocery store (The MarketPlace Somerset) that sells wine/beer/liquor right near Cambridge Beaches. You can ask your taxi driver to stop on the way from the airport or it is a 15-minute walk from the hotel. There is a fridge in each room!
The ferry is a fun way to travel around the island! The closest ferry terminal is Watford Bridge, and tickets to downtown Hamilton are about 5 dollars each way. The link below shows the schedule and routes. https://www.gotobermuda.com/sites/default/files/2024-04/summer-ferry-schedule-2024.pdf
