It's a question cottage owners hear all the time when they invite guests, "What should I bring?" A bottle of wine is always a good bet, and snacks are also great! Muskokaregion.com said, "It's quick and easy for guests to bring some basic snacks for the group. Chips, fruits, veggies, dips, all travel fairly well from the car to the kitchen, to the dock. Easy, appreciated." They should also bring their own supplie such as towels, sunscreen, and a hat if they can. Don't be afraid to ask them to pitch in!
