I'll keep looking but I think that's doable. We need to make sure we'll have those 15-ish people...
I'll look into properties and select some likely candidates.
The only caveat I would have about CO is opportunity for day trips.... With Florida moot, the attraction of day trips like Disney or Kennedy were good.... I'm not sure those mountain cabins offer much to do if you aren't in the shape to hike ;~D (I bet there are horse trails around ;~D)
Now... the best times were just sitting around on the porch, so maybe we don't care, but Kennedy and other things nearby was neat to have.
