I think that's a great idea.. But obviously there will be some ( like my husband) who would hate this idea!
I bet these places are busy though, as the actual christmas time flies by so quickly... Great to choose your own Christmas time there any week of the year!
If Christmas was all year round then it would lose the excitement it has. What places like this may be good for is pre-Christmas celebrations. Maybe you can go there in September to get into the stockings of what's the come a couple of months after.
