It's so great to see that the world is FINALLY realizing that love is love...regardless of who it's between.
Congrats to the happy couple, first of all!
When I was helping to plan my friends' stag n doe (jack n jill, buck n doe, doe n' doe, etc), I was prepared to drop a lot of money, just to donate to the cause. I never asked to be reimbursed, because I would have just given the money back to them in any event.
Because we were the ones planning it, I budgeted a few hundred to blow on the couple and was happy to do it, because in the end, the stuff I donated ended up raising hefty coin for the cause. We had hockey jerseys, an iPod, a basket of Bath & Body Works stuff and of course a cooler of booze.
