Welcome aussie! You will absolutely love PV! Ive traveled a lot and PV is my favorite destination in the world! honestly I would not stay at an all inclusive in PV due to the abundance of fabulous restaurtants there. I stayed at the fiesta americana and it was awesome. it had a swim up bar, nice beach, beautiful rooms. the food at the resort is not that great and iIMO too pricey but its only a five minute cab ride into downtown where all the action is. It has a semi all inclusive option that included wine in the afternoon and hors dourvers but not a full all inclusive..
If you set on an AI option, buenventura is a popular choice and the golden crown and they are a fraction of the cost of dreams..Good luck and congratulations!
