The missus works at the marina and in the premier inn taking bookings, could of maybe swung a golfgti.co.uk group discount. I'll have a word.
Regarding other venues for bevvys, Hinckley town is a bit pants, might be better off ordering a minibus for those wanting to go elsewhere and head over to sunny nuneaton a couple of miles away.
The cars will be much safer in the carpark of the hotel rather than on an industrial estate aswell imo and even though R-Tech is quite literally a 2 minute drive from the marina the cops will more than likely see all these golfs in the night as it is off a main road and start hovering around like vultures in the morning. So drinking is at own risk the night before. Police really like keeping themselves busy around here at this time of year
