Not sure how old your kids are but the best place to do the plan is at WLV on Seven Seas lagoon. Renting at the YC the speed and space is very limited but I believe the age restriction may not be as strict. at WLV you must be 16 and licensed in order to drive the boat by yourself. The price has gone up and with tax it is approximately 254. We just rented in June/July and they are always a big hit. And it is for up to five people.
