has any one done this before
Yes many years ago.
the supplier will need to be from around there and be able to deliver
Normally the supplier is you and your in-laws
kegs of beer red white wine and some other spirits .
Kegs of beer in a Hotel, may be a difficult one.
if possible if un touched cases can be returned ..
This I suspect will be the difficult one.
Normally you buy from a supermarket or warehouse and deliver to the Hotel yourself, anything left over is returned to you or your in-laws. I have never heared of a company that will deliver and collect and refund you on the unused.
You can only be so cheap.
