im glad i found this topic, as i was about to ask the same question myself.....we just got back from a month in Cancun and now are considering PV as our next vacation stop.....i gotta say, we fell in love with Cancun and am worried that the PV beaches and water wont be very enticing in comparison.....what we liked about cancun was that if offered soooo much to do, to keep us busy for the entire month.....the snorkeling, the different jungle resorts to visit, the nightlife, the variety of shopping and eating options.....and cheap prices cab be found if you wander outside the touristy area and into downtown Cancun.......i know i would love the fact that PV has a more Mexican feel to it, but im worrying i may have less
things to do there when spending an entire month........the fact that i can rent an apartment for half the price in PV, may be the deciding factor when forced to choose between the two destinations
