Cook ribs the night before

I am cooking 6-8 racks of ribs for a function this Saturday at 1PM. I've never done this many at one time before. I have a Weber Bullet smoker and gas drill at my disposal. My plan was to smoke 3 racks at a time on the top rack for about 30mins-1 hour, wrap them in foil and finish on the gas grill or in the electric oven in the house for another 90mins-2 hrs. .........ooorrrrrr start them in foil and finish on the smoker. Any comments about using this process?

I am contemplating cooking them the evening before. Any opinions about that? Thanks.

For ease of operation, cook them the day before, then reheat (and sauce) on the onsite gasser or oven. You should be able to fit 6 racks in the WSM, 3 on each level using a rack or rolling them.

I've done 7 slabs of ribs on my 18.5" WSM before and it didn't take much longer than 3 slabs normally would.
I used 1 rib rack per level and rotated the two half way through the cook.
I spray the ribs down with apple juice every 25-30min.
