Thanks everyone for your thoughts. I'll contact the front desk directly. A few points of clarification:
I don't think they'll have any issues at all, providing their names are on the reservation (which you state they are).
Not all of their names are on the reservation. The first reservation has my name and the names of three of the four other guests. The name of one of my guests (as far as I can tell on the confirmation email) is nowhere to be found.

I will pick up most of the incidentals and if someone happens to empty the mini-bar, I can sort that out at check-out. I'm not too worried about these guys going nuts. I know them quite well and it would look quite bad for their relationship with my company.
