That sounds like fun! Sometimes, just getting into a new enviroment for a few days does wonders for everyone.
One of my brothers rented a motor home and drove down from Idaho. He had six kids, at the time. Now, of course, the number is 10 and I long ago lost track of his grandkids!
His daughter, who is the same age (I think) as mine, just became a grandma.
Some people really rush through the generations :-). My family has tended to have children later than average for several generations. I had my first baby at 24, and that was unusually young.
