I am also late to the party. I totally agree with A's observation....why do the memories and being together have to be one way ?
I am also impressed with Mr. T. And FWIW, 1/3 of your vaca every single year when you have a small child who gets sick and you need to take time off for sometimes ( phew, a run on ), is A LOT.
BTW, I LOVE camping. Tent camping. But it is a whole different experience with little kids. Like, bad experience, different.
For the future, may a I suggest a long weekend, like Memorial Day or Columbus Day where everyone goes somewhere and you alternate where you go? That becomes the tradition. Also, if there is a hotel or inn near the campground, you could stay there and drop by for a few hours at the site next time.
Keep being the nap Nazi. Because you are the one who deals with the consequences.
