As to your question about beaching the houseboat in a different place each day, I wouldn't recommend it. Moving and anchoring a 75' houseboat will take almost half of your day each day you move (depending on how far you go, how long it takes to scout out a new site, and the efficiency of your crew). You'll burn up a lot of time. Personally, I prefer to stay in one great place all week to maximize play time. Others may move once or twice during the same period. You'll want to think about how much you need to see a new vista from the houseboat versus sightseeing via kayak or jetski.
Hope you have a great trip!
