When Ive gone to Puerto Vallarta Ive stayed at the marina by the airport. Check out my review on the spa in this area. Ive been able to invite my spa girl for more play time after they close. Of course I negociate before hand so there are no surprises afterwards. But it helps Im native spanish speaker.
