I like that idea starrysim. I think that I'll do the same
I know It doesn't make any sense to be charging us for open bar considering it's an all-inclusive resort. I have seen other people say that they didn't pay for the open bar for various functions that were close to the resort bars, and the guests just got drinks for themselves from the bar. We're planning to do our ceremony on the lobby balcony - as I understand it there is a bar just inside, so that will be perfect for the post-ceremony cocktail hour. We haven't decided where we're going the dinner, but we'll probably end up getting a few hours of open bar there, which I'm not too happy about. It's charged per hour, too! I probably won't commit to it ahead of time, I'll decide once we're there an I can see the set-up and layout of everything, and maybe try to get them to include it for free.
