Grew up on the river, but have been away a long time...

I grew up with a river rat as a dad, and then dated another river rat in my 20s. But then I took a break. So 20 years later, with a family of my own, I want to raise my kids to be lovers of the river life. Looking to find a multi-day family raft to expose my husband and two preschoolers to river life. Not looking for anything Grand Canyon worthy. We just want to float and get back to the best to nature (and I promise we'll leave our straws and disposable plastic at home).
