Not a Class-A, but I'll try to bite anyway.
When NOT using the camper? On an "as need basis", that's when. It just depends.
Available time, distance, money, and time of year (and interest at the time of booking) are all factors.
We enjoy our camper .. A LOT! So much, we basically live in it year round, sitting beside our 2800 square foot (single floor) house in the country. But sometimes, the camper is just not possible.
In the past, we have tried to take 1 trip a year, sometime in January, to go to a motel with hot tubs, swimming pools, and a lot of fun. Then we got our own Hot Tub in the house, and simply didn't have the need for that any more in a motel.
We did Wolf Lodge in Cincinnati, Ohio once.
Click here. It was a LOT of fun, especially with all the grandkids there in December.
Another time, my sisters and mother and all the nephews and nieces went to Branson, Missouri and we all rented cottages together. My brother in law brought his speed boat, we spent a LOT of time on the water.
One year, my wife and I got a good deal on a cottage rental at Nags Head, NC (Outer banks), so we drove (without the camper) and spent the week). The kids were much littler then too.
We've done 2 Carnival Cruises. One was the Western Caribbean and the other was the Easter Caribbean. One was over Christmas, the other was in March (about 5 years apart).
We've traveled to our daughters house (without the camper) a few times. She (then)lived in Iowa. She now lives near Kansas City, Mo. We did take the camper this last Summer to visit her in KC this time.
We not opposed to going anywhere without the camper. But as much as possible, we always take it with us. The exceptions are "exceptions" when it's just not feasible or doesn't make sense.
