Ugh, this is so stupid and frustrating, but we never thought to exchange last names and were planning on exchanging emails the last night they were there and we ended up not being able to make it to our final meet up before they left. All I know is her name was Sabrina, his name was Chris, and he was in marketing. I believe they may have been from Long Island NY, but honestly we weren't didn't talk about that much, because none of us cared. We were on vacation and having a great time.
