I've caused myself a dilemma and am wondering what type of party you all would prefer . . . if you were guests.
This concerns my DD#2's graduation party. She doesn't want a fancy-schmancy dinner party. She would prefer a back-yard BBQ party which is fine and dandy. We throw some great back-yard parties!

Normally our parties are on Saturday and start at 1-2:00 and last oh, say, until the beer runs out.

. . . Not saying that everybody get's sloshed (they don't. They are responsible drinkers) but saying that everybody gets a good
long time to relax with family and friends that don't see each other very often at all (maybe twice a year.)
My dilemma is twofold:
1. The party has to be held on the weekend of graduation due to both Grandmas living out of state. They are invited to the graduation ceremony (yes, DD#2 decided to walk

*) and I can't really expect them to come for the ceremony one weekend and then come for a party on a different date.
2. A band that DD#2 really likes and wants to see is coming to town for 1 night only. Yup. The Saturday before her graduation. In all of her (almost)18 years of life, she's never been to a concert. You should have seen the glow of appreciation in her eyes when I told her that I bought her 4 tickets.
Soooo, if you've made it this far

. . .
If I hold the party on Saturday, DD#2 (and DD#1 who has been invited to go to the concert) will have to leave by say oh, 3:00.
It would be really rude for the GOH to leave her own party, right?
At the same time, all the guests get to stay until whenever . . . relax and enjoy the company of other guests.
I could start the party earlier (10-11ish?) and do a brunch type of deal, but that would mean that the Gparents would have to start their drive much earlier in the day.
I can have the party on Sunday after graduation, starting at like 2 or 3, but I know the rest of the invitees work on Monday and may feel that the party is rushed due to their own schedules. I know that I like my quiet time on Sunday evenings, and am sure that guests feel the same.
(If I do the party on Sunday, I would take Monday off and definitely not push for people to leave, but there are the guests to consider.)
A 3-4 hour party with these people is unheard of. I really would like for everybody to relax and enjoy the time together.
Yes. I know that I caused the dilemma. But since it's already done, as a guest, which party would you prefer to attend?
*that was a different post in time for a coffee break. I'm glad she decided to walk.
