I agree, choosing a resort is very daunting (and tough since you have to go off pictures and other people's advice)! I walk you through my process!
Once we decided on a destination wedding, we needed a destination. We chose Mexico because of the cost (more bang for your buck than other Caribbean spots) and its proximity to the state/ease to travel there. Once we chose Mexico we met with a Travel Agent for some advice.
We went with Legacy Travel because they specialize in destination weddings (and they have an office in Chicago where we're from). If you don't have an agent, I highly recommend it, as they take care of ALL the booking of your guests and make sure all their travel arrangements are taken care of, so YOU don't have to worry about it.
When we sat down with our agent, we told her what was important to us and she recommended a handful. She told us the pros and cons of each, and also the cost of each. Honestly, I can't remember the name of the others we were looking at (I think one was a REAL resort??). We ultimately decided on Azul Beach for the following reasons:
-Size (It's very small, and this was perfect! It meant we were able to spend time with all our guests, and we were all running into each other the entire weekend. You can walk from one end of the property to the other in less than five minutes. This was also important to us for our elderly guests, including a 92-year-old grandmother.)
-Accommodations for kids (We knew we would have guests with small children, and the service for the children is outstanding, and something that sets them apart in my opinion. They have a great Kids Club, where two of our guests' kids LOVED and cried everytime they had to leave! They have everything parents needs for small children from strollers, to toys, to baby Gerber food, to high chairs, to bottle warmers, everything!)
-One wedding a day (I had read some horror stories about the larger resorts that do lots of weddings in one day. This appealed to us, as it means the staff is only concentrating on you and your guests on your day. :-))
-Proximity to the Cancun airport (We weren't interested in anything too far from Cancun as alot of our guests had to take multiple flights already to get there, but we also didn't want to be right in the "craziness" that can be Cancun. It's no lie that Azul Beach is only 20 minutes away. From the time we left the airport, to the time we pulled up to the resort, it was about 20 minutes, maybe less.)
-Beyond that, our agent RAVED about it as she had been there many times. After reading about Azul Beach and the other spots she recommended, it was the clear winner based on other brides, and just other hotel guests. Take a look at the Trip Advisor reviews. I will say, if you want a "party place" this is not for you. It's a very quiet, peaceful place both during the day and at night. All the entertainment is usually over by 11pm, and only one bar stays open late (1am).
It was the perfect little paradise for us, and all of our guests loved it and had nothing negative to say. Hope this helps!
