We have many reasons... But the huge on for me is I have just always pictured getting married on the beach. I feel most at peace when I'm near the ocean, I can't imagine anything else! After we went on a trip to Cancun last year he was 100% sold, so it has been what we've wanted even before getting engaged. But the other reasons:
1) He has a HUGE Dutch family, and we simply could not afford to have an at home wedding, we are footing most of the bill ourselves so it just isn't reasonable. Our $12,000 budget wouldn't get very far up here!!
2) Our families are super spread out. We are here in Edmonton, most of his fam in Northern BC and mine in the US so people would have to travel regardless. It makes more sense for everyone to gather in one spot
3) we both have divorced parents, so having a full week to spend with everyone ensures there are no hurt feelings about spending time with one and not the other, etc etc. Those with split parents will understand what I mean I'm sure!!
4) I don't get to spend a ton of time with lots of my family and nor does he as everyone is far away, we love the idea of getting to see everyone for an entire week and really spend QT with everyone.
