About an hour, of course it could also depend on how many ornaments are ahead of yours and what time of day you are going. There was one time where we were there at night (about a half hour before close) and they said it wouldn't be done until the next morning, but since we weren't planning on coming back to DTD that trip, they sent it to our resort when it was finished. Normally when we want something personalized there, we would go to the Christmas shop first thing so we can leave it with them while we are enjoying our day there, then pick it up before heading back to the bus stops.
