I realize your post is from the beginning of november, but hubby and I just came back from a week in Puerto Vallarta and to let you know dont eat or drink the water anywhere but your resort and only then if it is purified, use only bottled water and make sure your food is piping hot when served!!! We came back on the 13th and I have been sick since the 14th (its now the 22nd) I am currently taking two antibiotics and pain meds for an as yet undetermined illness (doc thinks its probably a parasite from eating or using the bathroom in downtown .). I will tell you that we had a great time and relaxed a lot but I wont be going back anytime soon!! Good Luck and enjoy.
