I would be more worried about towing the wave runners than the boat, by the way. Read up on the towing requirements, since some models require you to pinch off the water supply since pushing water through the jet pump can cause the pump seal to leak, filling up the boat with water and sinking it. I know SeaDoo is very susceptible to this, but I don't know about others.
We beach our houseboat. Prior to bringing it in, we pull everything off the back of the boat. This is an absolute must, since even if you were to catch the boats as they come in, you still have spinning props down below and they will eat your tow lines quickly. A fouled houseboat prop will ruin your trip. Prior to beaching, take the houseboat to idle speed, pull in the boat and wave runners, and have them disembark. Have the wave runner people get on shore and help you set your anchor lines. Houseboats need very secure shore anchorage if you are going to have any kind of wind or wave action. Anchorage is my biggest concern every time we take the houseboat out. Every time you think things will be fine if you go light on anchorage, something will happen to make you realize it is a fools game. Last year I thought I would be fine placing just two anchors on each side of my boat, but lost both on one side in a wind storm. I was tied around big rocks and the rocks exploded. Causing me to start drifting. Fortunately, I had started the engines already and was prepared to counter the wind with my props. The only way you can do this though is with proper seamanship, keeping your anchor lines orderly and free from the area of the props and making sure there is nothing that would cause you to damage anything or any boats you might have tied to your houseboat.
Good luck on the adventure! We love house boating. In my opinion, there is no boating/lake experience better than house boating. There is also no experience more terrifying when things go bad, so be prepared for anything.
