Graduation - Is it normal for whole family to go?

[DalmationDots]

DD graduates this summer and we were talking this evening about Graduation.
Can anyone advise me how many tickets it is usual to get? Is it the norm for just parents to go or do siblings/grandparents go too?
DD's father is not around anymore so if it was just parents then I would go and DD would like to ask either my mother or her paternal grandmother to go as a 2nd guest, sort of in the place of her father. It is likely her paternal grandmother wouldn't be able to come though.
If her brother is around he may want to come too.

That would mean she needed 3 or 4 tickets...
Or is it usually just two tickets per student and for just the parents to go?
Thanks!

I graduated in 1981 but didn't go as my parents weren't interested in attending.

NotaLondoner I have a couple of friends who didn't attend their graduations. Mostly they were working too far away and it was logistically difficult (and expensive) to get back to university for a single day. It hasn't had any adverse impact on their lives, and I don't think any of them regret not going.

A lot of people only go due to family pressure as the family want the nice photo op. If you don't want to go, then don't go :)
