Lynn,,what i'd do,,is reiterate you want non smoking. Then,,if your room does smell like smoke,,ask to be moved. W/my brothers room,,it was the weirdest thing. It didn't smell like smoke until the following morning. The day we arrived,,and that evening,it didn't smell. I walked in the next morning,and said "whats that smell?!" We thought maybe it was the in the sheets,and didn't come out til they were opened up,but that sounds silly. I noticed it for the rest of the visit. It wasn't a "fresh" smoke smell,,but a "stale" smoke smell. Each room seems to have its own a/c,so i don't think it came thru there. Our whole floor had the non smoking sticker on the doors,but i swear i saw a gal smoking in her doorway once. The hotel can't do much,i guess,if they don't see it. But if your room smells,,ask for a different one. Our room didn't smell at all. And they're very accommodating. You'll have a great time!!
About the room safe,,i don't know the exact dimensions,,we didn't use it,but i remember thinking "man! that isn't very big". Its shaped like a rectangle,,and is quite thin. Hopefully Tyler can give exact dimensions.
