Lake Powell in October is really wonderful. We were worried about the cold, but it was really pleasant. In fact, it was nice not being sweltering hot and sweating in your sleep! The days were warm, the nights were cool, and the water was tolerable.
This trip is magical for the kids. Because we haven't been for three years, it was Fisher and Quincy's first trip. They were in heaven, along with all the other kids. We packed 10 adults and 15 kids on to a houseboat. The quarters were a little tight and the bathrooms get a little stinky, but there is something magical about secluding your family away from the world for a week.
Because it got dark so much quicker than in the summer, we had a lot more time to spend on the boat in the evenings. One of our evening activities was decorating Halloween sugar cookies. Those are a lot of happy, sunburned kids!
