It is not the licence of selling alcohol which is worrying, but the fact many people go over the top drinking in front of their children. Then they have to drive!!!
It is still a place where families take their kids to see the museum and the gardens, not a festival site like glastonbury. There are alrady so many pubs nearby serving alcohol!
I liked the idea they had last year of the open cinema. Perhaps something like that (you pay towards it), would nice and give the opportunity to make more money.
