When do you suggest people commit by?
The day before!
Haha, but only half kidding.
I am proof positive that
@NinetyFour is correct. By the time I decided I was actually going, most people were already there. I left on Sunday morning from Seattle and arrived Monday afternoon. While I missed the weekend fun and some of the folks who only came for the first half, the few days I did have were AMAZING. And if you have a tent or a car you can sleep in it is pretty easy to find an extra corner in somebody's site to crash in --
@deborah generously allowed me to share her cabin the first night, I pitched a tent next to
@shadowmoss the second night, and then with help from
@Dicey I got my own cabin the last night (had a long drive to Denver the next day and needed to be well-rested -- the website said I couldn't book just one night but Dice helped me sweet talk them into an exception).
So, by all means book a site in advance if you can, but not having a reservation isn't really a barrier to joining the fun -- join the chat group and most likely somebody will be able to squeeze you in.
