prepping cooked brisket for potluck at work

You guys were very helpful giving me tips for a pork butt I made for super bowl potluck party at my work.

Now, we are having another one for opening day of the baseball season.

I am going to do a brisket. I will cook the brisket on a Saturday or Sunday, and the potluck will be on the following Friday.

I do have a vac sealer.

So, what do you guys recommend for this?

I have some chafing trays I can hold the meat warm in at the party, I was thinking of slicing it up and putting in that and serving it with some kind of buns

Also can use a crock pot, but I dont want the meat to fall apart in it, I am not sure if it would or not.

thanks again!!!
