To build on that, i would not worry about Ana. She is great and if she is not answering is because she is very busy. FYI, calling her almost always worked for me.
I am adding my thoughts on your questions in red:
1. Are there discounted prices for children? We have children coming from 15 years old to 2 years old. I am going to say yes, however the amount of the discount may depend on you're booking. Example: a whole package that includes flight, transfer and hotel (typical for Canadian brides like me), OR doing the flight and hotel separetly (typical for US brides). Our group is booked through Transat Holidays and yes there is a discount for children 12 and under. The amount depends on the adult quote, but from what I can remember is was a few hundred dollars less. I am a US bride that has the guests booking separately the flight and hotel and have received discounts for kids below 12 years old. I believe kids below 3 yeras old are free at the resort. I alos have lots of kids coming from a few months old to 12 years old. Our guests have found really good deals with Apple Vacations for the full package, so that is an option as well. I am not sure what their policy is for kids. For meals I think there is a slight discount for children and they have special children's menu if you want
2. Where are the locations we can get married? I saw pictures of the beach, the terrace and the rooftop terrace. You're right, but the beach has 2 locations. Beach on the Coral side (I've heard this one is busy with a lot of hotel guests). Beach on the Turquesa side is more quiet, however there is a not so good looking fence separating the hotel from the next property....but it's a lot more quiet than the other beach location. Lobby Terrace, this is where I'm getting married so I love it ;-) The other Terrace location looks good in the pictures, however when my TA visited she said the Teen Club is right around the corner and there are tacky murals painted on the walls. The three options you mentioned are the ones that I know about as well. I am having the ceremony at the chapel in Puerto Morelos and then the cocktain hour and reception on the lobby terrace
3. What are our options for having a sit-down dinner after the ceremony? Beach; Pool Patio by the outside bar and lounge furniture; Upper Terrace next to the lobby terrace; and Lower Patio below the lobby terrace where the stairs come down. Oh there's also a "plan b" indoor banquet room. Restaurants are also back-up indoor options but I think they are not 100% private
4. When is the best time to get married? We were thinking around 3 PM. It depends on the time of year you're getting married. Jan/Feb the sun sets earlier and as the months go on the days get longer. Check out this website that shows typical sunset times based on the month of the year. http://cancunmap.com...cun-sunset.html I am getting married in June and the ceremony starts at 4pm, cocktail hour at 6pm and reception at7pm
