Have you been Bonvoyed?

We just stayed at the Westin Resort & Spa in Puerto Vallarta. When we added the 3rd person, it added an extra person fee. For a 3rd person in a double, partial ocean view, low floor, balcony. (Which no way you can see the ocean) $65.00 a night extra person fee. When I called to ask do they get the breakfast, what is this for - I was told IN CASE THERE WAS A FIRE they would know how many people to account for. We got 1 glass in the bathroom, 2 bottles of water, 2 sets of towels. I was told it was a Marriott "thing" #bonvoyed
