hmmm to invite or not to invite?

one of our friends friend (I have hung out with the girl alot) and we see them every now and then. just got engaged. yesterday we all hung out and they were telling us to have our passports ready bc its gonna be in the bahamas in 2013.

we weren't going to invite them, but now do we have to? Another destination sounds amazing, and we def have time to save for it!
