Nope, I have not called the GF front desk about it. I wish I would have thought to check while I was there, but I didn not even make it into Sago to peak in a room when a maid was in there (I did this in Boca Chica, though). Boca Chica seemed to have the slightest smoke scent, though.
I thought that after renovation they had switched Boca Chica to non-smoking, and then the 4th and 5th floors of Big Pine Key and Sago Cay became smoking, but walking around Big Pine Key all the rooms had a non-smoking sign on them. Boca Chica had no non-smoking signs on the doors, but by the elevator it did say designated non-smoking floor (not sure if all the floors had this or not).
I'm trying to decide which building to request for my next trip! I really like the way the Swan theme is decorated, so I'm thinking about requesting Sago. BTW, Tgr, do they (people at the GF)pronounce Cay as cay or key?
