Another horror wedding saga: a second destination wedding.

I know this situation comes up a lot in this group/thread but I have to say it’s very cathartic to see the consensus that this is bullshit. My SOs brother got married last year at a courthouse wedding, it was cute all of the family on both sides attended and we had a huge dinner afterward. Honestly that should have been the end of it but this is where it started to stress the shit out of me and piss me off. Theyre now doing a destination wedding at an all inclusive resort in Cancun where 90% of their guests must attend. The cost of the resort for my SO and I for the suggested blocked dates is $4,000!!!!!! The minimum stay is 3 nights and it still adds up to $1,700!!!! Not to mention the flights. On the invitation at the bottom (“grab your passports!”) it says you may wish to put multiple guests in a room to save money…well only two adults are allowed in a room and it’s saving no one money anyway, I think this is ABSURD to expect this of people. Let alone to suggest sharing rooms? They also included a wedding registry on their invitation. And the bridal shower. And the bachelor party. This is all AFTER THEYRE ALREADY MARRIED. Make this your freakin honey moon, don’t put the cost on the guests. I think their room is free if they get the minimum number of guests. What sucks is my SO is also his brothers best man and feels obligated to go. I feel like this sham second wedding is greedy and bullshit and I don’t want to go. My SOs mom is freaking out at us for not wanting to go. I have no idea what to do and it’s stressing me out!!! I’m so angry at them for putting us in this position and I resent them so much…
