mike0479 - Depending on your sensitivity to temperature, 3mm may be fine this time of year. I'd bring a hood or hooded vest just to be sure. Most of the shops have 5mm rentals, but some are so compressed that they are prob more equivalent to 3mm...
dixonk - I'm usually in PV in December and the water temps tend to be mid to low 70s F. Expect similar in Nov (mid 70s F).
The Hard Rock, I believe, is in Nuevo Vallarta. I think there may be a shop or two nearby, but most dive shops are in downtown Puerto Vallarta or Marina Vallarta. Nuevo Vallarta is a distance from PV proper. Some shops will pick you up with boat/car, or you may need to take a taxi - I would inquire with your shop on best means of transportation.
