In a similar situation. My friend is getting married next month to a girl from Maryland (He's from Charlotte).. As per Greek custom, the wedding is being held in the bride's hometown. I'm in the wedding party, so I'm going, even though it's gonna be tough. And I went up for the engagement party last September.
Well his brother and some of the other guys are trying to throw a bachelor party, and they've been talking for a while about making it a whole weekend trip, going somewhere like Cancun and shit. I made myself perfectly clear from the beginning that I don't think that's a good idea bc a lot of people, including myself, won't be able to make it. Well they finally decided they were gonna go to the beach, and I told his bro I wouldn't be able to go due to lack of funds (more on that in another thread in a few weeks )...and having to work because I currently don't have any help at the restaurant. He told me that was "fucked up, but ok". luckily it was over text, so I couldn't punch him in the mouth. But I did tell him off.

That said...I wouldn't go. If you hold something like that out of town, you can't realistically expect that everybody's going to make it. If they have a problem with it, tell them to suck your balls.
