That is actually not Sandals, it's the Royal Plantation. That is the resort where we are getting married. It is owned by Sandals though, so I'm assuming it was easier for them to promote Sandals as a whole then just Royal Plantation.
When we watched the movie for the first time a few weeks ago, I noticed the peacock and thought to myself, hmmm that looks like the Royal plantation but then they showed the resort more I started freaking out, because it was it. Great ending to the movie for me!!!
