We had friends who went just after Christmas. They basically told their kids that “most of Christmas is the trip,” and just had small trip related gifts.
We had some friends who spent Christmas in DisneyWorld. They said it seemed as though half of Asia was there with them. ;o) But they loved it. Their youngest was in 4th grade at the time.
We've never had any desire to go to Disney or any other other large theme parks with the kids. they never expressed any desire to go, either. We went to Busch Gardens in Tampa a couple of years after we married, but didn't like the crowds, etc.
