Shan, your 3 and 6 you old can ride with you and another adult. They will only hold 2 people each. We have taken the water mice (now called something else I don't remember, I think Sea Rays) a few times during each trip. Our kids love them. They will even let the kids ster the boats as long as the adult is in the drivers seat. A few times my husband was unable to come with us so I took either a canopy boat or a pantoon boat that would hold all 3 of us.
