Okay, here's an idea. We booked a 25 ft. cuddy cabin to putt around St. John's and had a blast. Your kids are at a good age to do that. Only negative to some people is that you buoy at some points and you will have to climb/jump into 20 ft. water. Was not a problem for my kids who are all very good swimmers. The place is out of RedHook - you can catch a cab from the ship and arrange for the cab to pick you up around ??? time (worked really well for us). Anyway, if you're interested in this and want the name of the boat company, pm me; they have a website. Some friends of ours who booked with them last time are using them again for their August cruise.
