It will be fun, Norm. Puerto Vallarta, MX is one of my favorite places on the planet; and I've been around it a time or two already.
Highly recommended if one wants to escape sub-zero temps for a while. Cheap. Clean. And for some reason, no bugs! :)
While you're down there, have a look out your hotel window about 5:30-6 am. That's when the bug man sprays everything down so you don't see em when you hit the beach.
