In Puerto Vallarta, when you talk about layering, you're talking about what shirt/dress/tunic/maxi you're going to layer over your bikini. It's pretty amazing and disorienting at the same time. For example, I know that it's winter and there's even the smell of pine from the Christmas tree in the lobby, but I can't muster any holiday joy when my eyes are burning from the rays of the sun and the nice pool man keeps bringing me one frosty "Miami Vice" after another. #Vacationproblems.
