Parents/bridal Party Gifts

I think i would still give them their gifts if they are still gonna be in the ceremony and standing up there with you

I would give them out the morning of the wedding.

Traditionally, B and G either give gifts at a RD, OR host a meal or dinner and drinks , homestyle or restaurant and have just BP and couple, OR
BP and SO if a formal couples dinner thing. Before or just after the wedding. Or, bride does something with BM, Groom does something with GM, separately or together. In fact, when gifts are of unequal sizes, because some people did so many helpful things and others the average, etiquette says you do not give the gifts in a group situation at all, but privately. And only have a dinner, lunch, tea, cookout with the group. Gifts at a private time. Parents don't traditionally get a gift at wedding time, beyond the photo album or framed photos after the wedding. You may, but not usual. The recent trend to give everyone gifts in a steady stream is not traditional. And ettiquette says, if someome gives you a gift of money for the wedding, you need to write a letter, but not use a gift to thank people for a gift.However, a parent or other family member may have gone way out of their way to do many little services ( hand addressing and stuffing invitations, help with DYI or flowers, cooking or favors, picking relatives up at airports, etc. ) Then a gift with a thank you note is due. But if parents are getting different things, give those gifts privately. Even if you do have a RD, you would observe the rule of not embarrassing anyone by giving unequal gifts .
In short, you are fine to choose a meal, a group, or do things singly and privately. Whether or not you have an RD. If bridal party will be at the ceremony, this is a good time to see people individually, or in whatever small group you choose.
