I did not expect 90+ responses.
Anyway, it is NOT a destination wedding. The bride is from the area where the wedding will be held. It's just not in an incredibly convenient place from the East Coast, and there happens to be a major event going on the same weekend (which the couple did not know when they picked the date). The wedding plans themselves are very modest, but also super-cool. I'm amazed at what this couple put together on the budget they did and would love to attend the wedding. If it weren't for the family situation, which has already thrown a wrench into multiple travel plans this year, I'd definitely go regardless of cost.
And, no, the bride and groom are not "society" people; they're people who spent years in school and racked up tons of debt to do low-paying but really important jobs that they believe in (teaching & research). Neither of them is from a well-to-do family, which could make this the biggest wedding gift and a bit awkward

. I would never expect reciprocation, and if Sweets and I ever get married (which neither of us is in any hurry to do), there will be a very strict no-gifts/charity-only policy. That said, it could throw off the dynamic of our friendship.....
Maybe $500 is safer, and I can put the other $500 aside for some other occasion. Sweets' first reaction to my idea was

(even though I'd be the one writing the check), so I'm giving that a lot of weight, too. Maybe we could take them out for a very nice meal as well.
And, of course, there would be no strings attached to the gift. I mentioned honeymoon because I know they would like to go on one but can't right now, but they can do whatever they want with it.
Anyway, thank you for all of the input/advice!
