We have to provide our own drinks at my reception site. Since Pina Coladas are my favorite, we will be serving them. The problem is that our bartender said that we will need to rent a machine to make them. I have no clue where to find this or how much it would cost. I checked a local rental place and they didn't have it. Has anyone had this issue? I thought that we could just take a bunch of blenders, or blend them up ahead of time, am I wrong?
