We're married 38 years. My parents paid for the food at our reception, about $400. FIL paid for the liquor. DH and I paid for everything else: my gown, invitations, flowers, photographer, band, engraved napkins & match books ( it was the thing back then, lol!). Our honeymoon was 3 nights in Toronto, a 90 minute drive away, we paid for that too.
Our DD was married 7 years ago at a large banguet facility with only 100 people. We paid for everything related to the wedding (invitations, d.j., her gown & accessories, venue, sit down dinner with passed hordorves, Vianese table, flowers, cake, favors, etc) except the photographer. DD & husband paid for that. His parents paid for the rehearsal dinner (12 people total) & the honeymoon. We also got hotel rooms the night before & night of wedding for us, DD & our DS. Unfortunately, the marriage only lasted 2 years. DH says she's on her own for the next wedding, lol!
DS just got married this past summer. They had 200 people at a trendy downtown restaurant. I don't know the total cost but her parents paid the majority of it. DH & I gave them $6K to spend as needed on the wedding. We did the rehearsal dinner at a waterfront restaurant for 30 people with a buffet dinner & 3 hour open bar. Total cost was about $2600. Again, we got hotel rooms for ourselves & our DD. DS & DDIL paid for their honeymoon.
We also gave each of them $1000 as a wedding gift. We were so happy to be able to help give both our kids the weddings they wanted. We enjoyed everything about both weddings. Actually, my DH, who isn't very social or outgoing, said DS's wedding was the most fun he's had since our own wedding!!
