Help me name this movie!

Tweet

There is a movie out there that I remember seeing advertised a little over a year ago and I cannot remember the name of it. I have tried searching online too and just can't figure out it. I'll give you the clues I remember and see if anyone can help me out!! The movie was a horror movie about several couples going on their honeymoons on this island. Obviously with it being a horror film, people die. And like I said I remember it coming out in theaters about a year and a 1/2 ago. Anyone have any ideas?? And to help make this more of a discussion - What are some of your favorite horror movies and why? I'm looking for some great movies (including the one I can't think of the title for) to watch on my instant Netflix this weekend!!
