Having Best Man and Moh walk alone

That sounds perfectly fine! We had everyone in our party walk alone.

This is actually a fairly common processional arrangement.

I also would make sure not to do any dances that require people to dance with people they're not comfortable with (and tell your DJ!)

We had everyone in our bridal party walk alone, and that was before Covid. I prefer that over escorting, so I don't think it is weird at all.

My MOH is walking alone, I think its okay.

Absolutely normal!

when i was MOH, i walked in alone and everyone else was paired.

Perfectly normal! As long as they don't mind it and you guys don't mind it then go with it.

I don't think it weird at all.

However, consider how they will leave. I have seen many variations of the bridal party & groom party walk in, but usually everyone walks next to each other when it's over. Perhaps, have them walk one after the other, or something.

It was kinda odd cus for the reception i walked with him. but again, you can do the same type of procession for the grand entrance as you did for the ceremony
