Club Regina- P.V., Cabo and Cancun-- have ashtrays in the units- do not appear to have smoking and non- smoking rooms- and not seen any no smoking signs. At different times- we have smelled either cigarette or cigar smoke from an open window or balcony- but never has been a problem. As a former smoker- I am very sensitive to smoking odor (you know a reformed anyone- is the worse in the world) - I have not smelled an odor of stale smoke in any of the rooms- must be because of the all the stone, tile, cement, windows- and very little fabric for the odor to stick to, plus- the housekeeping staff- really scrub the units on a daily basis.
Only have stayed a Mayan Palace once- really do not remember anything about thier policy re smoking.
