Jewish weddings - what order does

I believe first the groom and his family, than the Grandparents, than the cousins/brothers/rest of family , and than the bride w/her parents...

Not positive though!

I think it is grandparents, best man, groom w/ parents, bmaids with ushers, maid of honor, bride with her parents...

Not 100% sure however....

My rabbi/friend who is marrying us said it's up to us
We are having Grandparents 1st b/c I don't want them waiting around to walk if it's hot

I think we are having them, the groom & his parents, the bridal party & me w/ my parents

She gave us different options depending on who is in the bridal party
