Welcome, Lisa! I married at Las Caletas last June. We stayed at Dreams but several of our guests stayed at Velas Vallarta. We spent an afternoon there hanging with them.
The place is huge and beautifully decorated. I went to 2 rooms, one was a 1 bedroom and one was a 3 bedroom. The furnishings/decor was flawless and they even stock the kitchen with snacks. The balconies were really large too, it was like a really nice apartment. My favorite part was the pools and the lazy river, just awesome. To be honest the beach sucked, but all beaches in that area kind of suck...you have to go South (like towards Caletas) to get nicer beaches. It is pricey but unless you have big ocean swimming guests going, they will be impressed. I hear the food is excellent. We had a member of BDW marry there last year, search for her review & pics.
Dreams Vallarta is usually slightly cheaper (but not by much), and I highly recommend it. It's more intimate, the beach is better, and it's a Dreams property which means it's pretty damn wonderful If you search the site (above, right) or look in the PV section you'll find lots of info on PV hotels.
Happy planning!
