Limo question....

Who goes in the limo?

Me, my mom, sister and a few of my bridesmaids, as well as FH and his brother will be getting ready at the hotel about a 5 min ride from the venue

I'm trying to figure out how big of a limo I need and for how long -prob just for the 5 min ride there and then to take us back to the hotel after.

But who has to go in the limo from the hotel to the venue?
Me and FH obviously
My sister - MOH
His brother -BM
parents? other bparty members?

I'm confused!

Usually bridal party and parents if you want.

We got a limobus. 6 BM, 7 gm, me and FH, 1 jr bm, 2 jr gm, 1 ring bearer, maybe my parents, and FMIL...just thought it'd be more comfortable to have the limobus than the escalade and it was only 100 more.
