My children will be 11 and 8 when we go next month. We will be at AS Movies, this will be our 12th trip in a value. (9th with the kids)
We typically stay 7 nights, we drive 1,250 miles each so add 4 more nights in a hotel room (2 stays each down and back) plus all the time in the car together. We are absolutely fine. If you want time away from the kids, I'd take the extra money and put the kids in one of the clubs for a few hours and have a grown up night with you hubby. That's what we do. And we love it.
I just don't see how a few extra square feet makes a difference (we stayed at CBR when the kids were 9 and 6)
