The wife and I (no kids for this trip) headed out Saturday afternoon. We got to the lake around 1:30 and were surprised to see no wait at the launch. We did some boating, hung out with some friends, went to dinner at a place on the water, then headed to the island to spend the night. The boat has a "camper-top" and the seats fold flat for sleeping. It was surprisingly comfortable and we stayed warm.
Here is the boat with the top on, I tried it out in the driveway to make sure I knew how it worked before getting there:
