We just bought a 1982 Airstream Excella with plans to renovate it and hit the road next year. I'm sure we'll still bring the tents for a few nights outside, but it will be nice having all of our creature comforts while we explore nature.
In our experience, and given the time of year especially, we've really enjoyed cabins-- like KOA cabins, for example. To me and my fam, we love to explore and be immersed within nature-based play, but extended nights are unapologetically better with some "sleepover comfort." That's where cabins--with tiny kitchenette, bunk beds, mini fireplace, & bathroom--come best into play for our young family. We hope to experience "roughing it" later.
Tent camping is our favorite family activity. We've tried several brands of camping gear (which can make or break your camping trip - hello, leaky tent!), and found REI has the best quality camping gear. REI sleeping pads are so cushy I feel like I'm sleeping in a bed.
