The parents are the type that they'd prefer to just have smaller dinner gatherings and "oh by the way we're having cake/dessert" to celebrate their 50th Anniversary and hate the idea of having to get dressed up or a big exhausting gala gathering where they don't really get to be present and savor the time with each and every guest (Ma also doesn't want to have to dress up). Barring "just skip it" being what they planned to do to mark the occasion, multiple small intimate casual dinner gatherings is more my parent's style (no band, no DJ, no hoopla, no centerpieces, no photo tables, no favors, etc.), this has been discussed for YEARS at this point. I'm on board because they are the guests of honor... Bring out my/DH credit card because if someone doesn't plan it soon nothing will get done (and DH wants to do this because he doesn't get to have one for his parents - he's the otherwise non-existent party planner that thinks all this stuff happens with a magic fairy wand being waved, so he's not projecting anything)... My other siblings and SIL "get" what's going on but have no opinion one way or the other except for one B/SIL...
I just got an ear-full from the brother who (SIL) wants one gigantic social gala event that the parents do not under any circumstance want (which basically would also limit out my Mom's side of the family and friends from "back home" who can't travel that far). It's the "strings attached" IMO being follow what the parents who are the Guests of Honor want in a party(ies), not the 600 person gala gathering that this sibling/SIL want instead... Is it wrong to have the string attached to our credit card coming out be "follow what the parents WANT in celebrating their 50th" not what that SIL wants??? My parents/I want STRESS FREE, my SIL, not so much...
