We ended up doing it in 4 days. It ended up being about 1200 miles round trip for me. But we really meandered on the way home. I was on a Tiger XC which is pretty comfortable but even so my butt was pretty unhappy with me by eod on Sun.
We stayed in hotels for this one. First night Killington. Second night Newport VT. Third night Lake George.
It was a haul but I'd do it again this weekend if I could.
