No. basically it works like this....
For those that rent out the 1BR "tree house" cabins like zoothorn, the pad is there's and there's alone. Technically IIRC, you are "supposed" to inform the cabins of how many folks are staying in each particular cabin and I believe that two is the maximum for the tree houses but I'll have to double check and get back to you on that because as mentioned sometimes they have additional futons or couches or whatever that others can sleep on. As far as I'm concerned......it's a don't ask, don't tell situation if you have a youngin' or a friend that wants to tag along. That said, if you do get busted, don't come screaming to me because I won't give a flying F.
Now, for those who are part of the reserved cabins it's a little different. Some of the cabins are 2BR and some of them are 3BR cabins and the way we had it hooked up last year with plenty of cooperation from the cabins was that a "party" or "parties" rented a room, instead of the entire cabin. Some of the rooms had an extra futon or couch that was actually put there intentionally by the cabins for additional sleeping accommodations.
So if you have [We'll use Toymaker as an example] James and his woman Angelic as well as his son, basically just request a room that has extra sleeping accommodations. If we don't know which rooms, we'll find out or I'm sure the folks who went last year will remember the layout. If we still can't remember, they are just a phone call away and the cabins have interior views on their website. Of course you do know that if James wants some "boom-boom", his son could always sleep on the couch if it isn't already "reserved" for someone.
To answer the question about whether or not he will cost any additional $$$? [If he or anybody else for that matter wants to come...] If the bedroom has the accommodations it's free because you have already rented the room. [For your knowledge the cabins note which room you will be renting so it's not a clusterfuck when we get there] This will be handled on a first rent first come basis. That said, if the additional guest is not welcome in the rented bedroom, then it will be up to the 2 or 3 "renters" that paid for their rooms as to whether or not they want to be reimbursed for a portion of their total amount due.
Remember, the cabins may "say" that they sleep 6 but they also [as stated before] have provided additional sleeping areas located throughout the cabins. I think Watershed 11 [the main host cabin] sleeps "4" but really has accommodations for 9 IIRC. Each cabin is different and additional information can be sought via a phone call to them or by checking out the website.
