No action required
Once you have kicked the punters off, they are not your responsibility. You have no (legal) power and no (legal) authority so my suggestion is do nothing other than hand over the PIL to the the relevant authorities. Getting involved without knowledge of local RFF procedures and/or the ability to communicate with them has the potential of making things considerably worse. So I'd stick the liquid contents of the bar carts in your trolley bags and zip off to the hotel.
