Rick,
our kids also went through the "I don't wanna go away with the "rents" (parents)" time in their life. (looking back, so did we..) Now, married, they have figured out that getting access to Mom and Dad's TS is awesome. Yes, there was an empty period where they wanted nothing to do with us on vacation, but not anymore. All their friends are very jealous of them when they go to Hawaii. My wife still looks forward to seeing them enjoy time with us there, even if it is because we know it is their cheapest option.
