I think it's pretty tacky to actually tell people what you paid for a wedding. Weddings are for 2 people usually. To a lesser extent, the Bride, and to a greater extent, the Mother of the Bride. So, if the Bride's fam is paying, then they can and should spend whatever the F they want. In my case, my parents also cared a lot about the wedding (had more of their guests than my wife's fam even though the wedding was in CO where she's from), and they paid for a good chunk of it. Her fam kicked in some, then yours truly paid for the rest. Considering it was effectively a destination wedding for 75% of the guests, we felt the need to throw a good party. Plane tickets plus 2 nights in a hotel, you are looking at ~$1k expenditure for a couple. Bused everyone to a nice venue, open bar, Surf and Turf, band, plus everyone was invited to the rehearsal dinner at Folsom Field.
The tough part is all the last minute crap that comes up, and stuff you forget about, like the tips for everyone.
