i think it depends on what resources you have to pay for the wedding with (including family support, if you have family).

i think if people already have the house, already have money in the bank to draw on, good luck to them how they spend it.

but if a couple takes out a big loan out to pay for that perfect day, that to me would be scarey. But then i'm the only person i know who doesn't have a credit card. I refuse to have one until i have the capacity to pay for it.
