I see no problem with a sale, especially if some Christmas items were a part of it (like the unreleased pink Santa hat). Everyone wasn't able to be online for the original Halloween sale either, but that didn't stop them from having one. Everyone isn't going to be able to participate in everything anyway. If you miss it, it's not their fault. People may be visiting with family, yes, but I think it's unlikely that most people won't have any access to the internet at all. I find that hard to believe knowing most players are teenagers and likely can't go anywhere - even for a day - without their phones, tablets, and laptops. Even if they can't bring their own, it's likely someone's going to have a computer somewhere.
