Just an FYI for anyone who may be getting married in/around December like we are...when we booked our date, Ana told me our ceremony had to be @ 2pm (another wedding was already scheduled later).
At first, I was really bummed because I wanted a later start time, but now I realize that maybe 2pm isn't that bad at all, since the sun sets @ 5. I feel much better now since I just came across this on Octavio Montes's website (photographer) under FAQs:
Q- I am not sure what time to tell the resort i want the wedding. what is a good time for ceremony in december? i want to have nice lighting for my pictures
A- Then The ceremony must be at 2:00 pm so we can have the couple session at 3:00 pm because the light start losing at 4:30 pm.
Anyway, I just thought I'd share in case that was useful to anyone. I definitely recommend (as many others have) checking the sunset times for the month you're getting married in, since it can make a huge difference in photography...
