Almost everything about this stay was great. Almost.
I enjoyed the pool and hot tub, I liked the mountain-style decor in the room (lots of carved wood), I was grateful to have a fridge in the room, there was a nice big table to work at, and the argon-oil lotion and shampoo were great. The staff I met were professional, kind, and helpful. The on-site restaurant and gift shop are impressive.
Thunderbird let me know before my arrival that its on-site restaurant would be closed that day, which helped me come prepared to feed myself.
After snacking on popcorn, I was picking up a few pieces I had dropped and noticed a couple of what looked like pieces of popcorn underneath the other side of the table. "Wow--I didn't think I had dropped that much--and how did they get over there?" I wondered. Alas, it was not popcorn--it was potato chips, left by some prior guest.
It worries me that something so basic as vacuuming was not done after (how many?) prior guests had departed.
That's my only complaint.
