What did you do when teenagers no longer want to camp?

We began to take them where THEY wanted to go; whether it be more rustic or more recreational. Let them bring friends and didn't go for more than a few days. OUr kids love to camp with us now in their mid 20's and never really stopped. Bought them a little pop up for their own hotel now. We would leave them at home after age 16 if they didn't want to come and have friends and family check to be sure there weren't any get togethers at the house. I admit though, we were very lucky to have them come 90% of the time.
