if you're wanting to do this one for the 100k contribution I'd suggest not bothering xD, you need around atleast 40-50 ppl to successfully do it, and none of these ppl can go afk. It requires questing alot and spending alot of money (though money doesn't really matter much lol) It's much more difficult to complete then the regular wedding. But if you wana just try it out, hey it's a cool one xD, your bride it's locked away in a cell and you have to save her hahaha
