Pros? Cons?Until fairly recently, I just assumed that we would have a couple of my cousins who aren't otherwise in the wedding just stand at the door and hand out programs and direct people to the left or right (or escort an elderly guest). No tux, no other responsibilities.My FFIL insists that the groomsmen ARE the ushers, to the point of only referring to them as ushers (which seems like a downgrade to me, but eh...)On the other hand, my uncle, who is performing the ceremony (he's a judge), insists that having the gm's double as ushers is a bad idea - that having them multitask will complicate things needlessly.We're expecting about 160 people, and have 3 gm's (plus best man) - and the plan is to have the gm's escort the bm's in the processional, if that changes anything. At a church, but non-denominational ceremony.The only other piece of info is that we all (including my cousins, the potential ushers) will be driving in from ~3hr away, and so if there is any delay in schedule (we do have lots of extra time built in, but worst case), my concern is that the gm's will take more time getting into tuxes, while the cousins will just need to slip into a regular suit, and so at the very least, we should have backups?Sorry for the novel - just want to cover bases. Thanks for any suggestions or advice.
