Looking to do the Lake Powell houseboat trip, renting one of the houseboats. I have decent boat skills, 20' outboard, and they seem OK with renting to me based on my experience, state boating license and skill courses. Any skill sets beyond 20' runabout skills I should read up on for running the house boat? Planning for five adults, five kids (2-10) on a 50' with a ski boat. Any advice people can offer on crew/size of house boat ratio? 54' OK? We are planning on the 54' Escape to get 2 bathrooms. Suggested route for first timers to make for easy cruising and good camp sites. We are hoping for this every night but figure so is everyone else. Would like to avoid the most crowded spots.
