Dear 82turtles and Rfinger :
Both locations are great,some people like the idea of the roof by the Tequila Terrace but not very good for dancing at leat not in high heels ....
The beach terrace give you more privacy because it is apart from the Restaurants area...the inly little issue is that restrooms are not close... check picture below , this wedding was at the beach terrace with buffet service and private bar.
While there are a couple other outdoor locations for a reception, the Beach and Tequila Terrace seem to be the primary ones. We saw a couple other wedding receptions on a deck outside a restaurant. They did what they could to put up linens to kind of block it off and make it more private.
We did the Beach Terrace, and it was a perfect location for our group! The one drawback I would say is you're a little bit further from the restrooms -- have to either go in the lobby or go in the restaurants. We went to the lobby one because there was a wedding on the Tequila Terrace at the same time as mine, and I didn't want to walk through their party as a short-cut to the bathrooms! Really wasn't a big deal.
As for the privacy -- the Tequila Terrace is right outside the buffet (separated by glass windows only), so there will likely be people watching from the inside. Other brides have said it didn't bother them, and they hardly even noticed. The Beach Terrace is nearer to the main pool, but it was more private due to the fact that after 5 pm when the pool bar closes, most people head back to their rooms to get ready for dinner and evening activities, so there aren't really people around. We did have some observers of the ceremony since our start time was 4 pm (early sunset with it being November). At first I thought it would bother me, but honestly I didn't even notice them -- little more focused on our own thing!!
And lastly, the Beach Terrace was an awesome place to dance!! No one had to worry about heels or falling in the slats, and lots went barefoot without having to worry about splinters as they would on the wood deck of the Tequila Terrace.
I assume it all depends on if there's another wedding booked for the same day/time as yours, but if you get there and another reception location seems like a better fit once you see the options, I'm sure they let you change. Really, both spots are fine -- it's more about you, your spouse-to-be and all your guests having a great time!
