Again this year we are offering indoor camping on Saturday night for those wishing to stay overnight for the activities on Sunday, or just to avoid a late-night drive following an evening of gaming and/or bardic.
The camping is in the great hall, and your "campsite" can be a simple or as elaborate as you like, as long as you do not try to affix anything to the walls or floor. Wrap yourself up in your cloak and lie on the concrete, throw down a sleeping bag - or put up your modern or period tent in any fashion that doesn't involve trying to pound stakes into the concrete! In the past, one family used backpacks in the corners to anchor down their modern tent.
There are electrical outlets along the walls for those with medical or other needs. Also, the hall is large enough that a campsite at the far end of the hall can be considered quiet camping. And parents, your kids are still in the same room, so you can actually come and play with the grownups without having to find someone to stay with them.
Just think - camping without snow, bugs, or windstorms, and flush toilets just down the hall. What's not to like?
