Why is it that any time someone expresses a desire to hang out without kids or dogs, 80% of the responding posts are people telling them that they're wrong for daring to have that opinion? I just don't understand. Personally, I agree with the OP. When I'm on vacation, I don't want to have to modify my behavior to set a good example for other peoples' children. I'd like to hang out with other adults and act like an adult without worrying that I'm corrupting the next generation. There are plenty of "Family-Oriented" CGs around, and plenty of "55 & Up", but I would love to see a few that are in between.
Oh, and if Disney World / Fort Wilderness ever has a "No Kids Week", I'll be the first in line.
