I stand corrected- the Olympic Terrace is the photo you have the link to above, and it is mostly private. The entry is roped off so other guests aren't walking through your area. Gabi is $$ and I can't remember what that includes.
We had our ceremony in the garden gazebo and our cocktail reception in the flamingo foyer and our reception in the apolo foyer, all outside, but covered (except the garden gazebo). I didn't want our ceremony on the beach though, so that is why I chose the gazebo. On the beach everyone stops to watch, which is ok, I just didn't want photo's of people in their bathing suits, ya know? Also, it can be really hot out there bc there is no shade. It can also be really windy so you are hooked up to a microphone. We had 58 guests, which I thought was a great number. We did the Aqua package, which had the plated dinner and our 2011 package included alcohol.
I think your idea of having your ceremony on the beach is beautiful. If you privatize Gabi, I would just recommend having your cocktail hour there, too bc in my mind it doesn't make much sense to walk to the Olympic Terrace for one hour, and then all the way back to Gabi for the reception - especially bc Gabi has a bar already, so the set up transition would be seamless, and they have a hard surface so you don't have to rent the dance floor. OR you could just do your cocktail in the center of the resort - by the big main fountain (forget the name - and they rope it off so random people don't walk through), and then have your reception on the Olympic Terrace bc it's also mostly private and doesn't cost as much as the Gabi. It also overlooks the main pool which is lit up at night, and the beach, and you have the cool breeze. Remember you're not going to be present for the cocktail reception - you'll be taking pictures, so you'll want some daylight left during that time so all your photos aren't at night.
Have you decided which wedding package you're going with? I mentioned we picked the Aqua package bc I wanted a plated dinner instead of a buffet. I asked for the Chill Out Chic linens though bc aqua and white were not my colors. We picked The Reserve to have some privacy from my MIL. Some of our friends and some of my family stayed there too and it was really great. I reserved that room, which wasn't an upgrade. If you get the wedding package and you stay 7+ nights then they will upgrade you to the next room level at either part of the resort. If proximity to the beach is important to you, you might want to consider staying at the regular part of the resort bc you either walk 10 min or take a golf cart ride every time you want to get between The Reserve and the regular part of the resort. I didn't mind and knew I wanted to stay at The Reserve, so it wasn't an issue for me. They also have their own restaurants/bars/pool/spa/gym, etc. I got my hair/make up done by Claudia at The Reserve spa and she was amazing. I didn't do a trial, just walked in with a pic of the type of make up I wanted and she did it and told her how I wanted my hair, and she made it happen. I used HDC Photo for our photographers and I can't say enough nice things about them. I didn't particularly like the guys that are on the resort, so I did a little research on here and found HDC and really couldn't be any happier.
If you have any other questions, don't hesitate to ask!!
