Like it's a bike gathering, I don't recall us really using a pool at any past events. It could get ugly.
When I used to go to Climbing gatherings with my X wife, (Hate to have to remind myself of that) They found a LODGE wherever they were to meet, they all chipped in on the Lodge, they landed with food and beverages, They owned the whole deal, Fire, Beds linen and kitchen area was there, showers, it was way too cool. Too bad we can't do something like that.
Far as hotels, They will only do so much for a group, and I have not been to a M&G where the roms were really reasonable or discounted. Hotel Clerks, Managers BS you, period, I have hours and hours and hours listening to them BS potential customers. (I stay in hotels 3 to 5 times a week for work) It's Poker to them.
They will rent one guy a room for cheap, and will not budge for the next. It's all in what you say and who your talking to.
Climbers are sorta next to mountain Bikers in the way they do things. Not sure Bikers are up to it.

ah well. Pin the
map, we will be there. Unless someone Pulls out in front of us.
