I think you'll be excited to know that I've been to this resort twice, and I never travel anywhere twice! It's absolutely wonderful! The food is amazing, the drinks are amazing, the staff is wonderful, the resort is GORGEOUS and the beaches (especially Sunset Cove) are incredible!
One of these times I was there for a wedding, and everything went off without problem. They got married at the gazebo but stuck with the dinner included.
I myself am now getting married there in November of 2018 We are opting for the private reception, it's important to us to have privacy as a group and a dance afterwards.
The blue lagoon is our choice as well! It's stunning and the views are gorgeous.
If there's anything you want to know about the resort, I can help! I would recommend booking everyone in the same building areas. Close to the lobby but no rooms facing the lobby, as it's quite loud at night and some guests may not be party people. We stayed in the 20 buildings and the 30 buildings. It's a massive resort so any further back is a lot of walking!
I got too excited and didn't even answer your questions, lol. We are looking at the Sapphire package too! Or the Love Pearl.
It's only covered for 30 people for the ceremony, so each additional person after 30 is $20.
As far as the private dinner, there are options depending on what you want, but it looks like a sit down served meal is $45 a person, none included so that's for each guest. If you have 50 or more guests, there is a buffet option!
If you decide to have a non private dinner, the first 30 guests are free and each additional is $20. (not a good deal at all)
