During Thanksgiving weekend sounds like a bad plan to me. It is a fortune to travel. It’s extremely crowded on the roads and in the airports. Hotels are probably very full and expensive. Some people obsess about shopping on that day, which I think is awful, but it is a tradition and having to get ready for, and go to a reunion would interfere with Black Friday shopping traditions. People plan to be with family over that weekend, not schoolmates. Not only the nuclear family, but extended family also. Some people have to work on Black Friday, it is one of the few days of the year that it is completely impossible for some workers to take off. Hotels, retail, restaurants, it’s quite a large group of people who have to work, no exceptions. The one thing I will say, is the people planning it I am sure are doing a lot of work, and trying their best. I guess the date works best for them, and since they have stepped up, they get to choose. Is it a smallish town school? I can’t imagine an urban or large suburban school picking this date. It reminds me of when my SIL chose the late summer for her sons baptism. Two weeks later and the flight would have cost me half. Instead of $800 each ticket, it would have been $400, because the tourism season would have ended. The weather would have been about the same, and no one in the family had small school age children that had to be home when school started. I was in my early 20’s just starting to earn a living, so that was a big deal for me financially, and in fact no one was rolling in money, and we were all flying internationally on my husband’s side of the family I’ve also heard of weddings being done over holiday weekends. I think they think people won’t have to take a day off from work, but it just isn’t true for a lot of people, and it is more expensive to travel. It just depends on each person’s particular situation I guess.
