Hello, we just got home from our wedding at FACC about 3 weeks ago. It was amazing and we could not have asked for a more perfect wedding! We had the ceremony on the beach and the reception outside in the upper pool/garden terrace area. They block it off to make it private for your party. We had 54 guests and did the private reception with plated dinners instead of buffet.
I got my hair and make-up done on-site. It's nice because the people come to your room to do it. I just showed them a pic of how I wanted my hair and they did exactly what I wanted. I am also not one to wear a lot of make-up and the eye make-up was a bit much for me (but I got tons of compliments and everyone else loved it). I think as long as you tell them or show them what you want, they can do it (show them a natural look). The guy that comes is an actual make-up artist, so he does this crazy stuff where he matches your skin tone.
Our guests booked rooms thru the 1-800 # that we were given with our "wedding group code". This helps so that the hotel pretty much hooks your guests up with better rooms/locations. I think it would have been easier for everyone to book thru Orbitz or Expedia, but you and your significant other also won't get extra perks (because the hotel won't know who is actually in your wedding group if you do it this way). We got hooked up to the master suite because of the # of people we had and also, all of our guests got up-graded to Ocean View for the price of Lagoon View.
Hope this all helps! I will attach a few reception photos so that you can see the set-up.
