It is true that you are sat in the cold watching the match as alcoholic drink is allowed to be drank in the restaurant or box. I don't think that they have changed the rules on being able to watch the match whilst drinking so the curtains are closed. You can watch the match on th TV in the rooms.
It is a completely different experience than sitting on the terraces. I personally enjoyed it but I was a guest of Eric Twigg (Matt and Lisa) and everything was free. It was my one and only lad and dad match in my life.
My dad really enjoyed it and sat and talked to Les Paigne reminissing or matches and old players of the Sunday league. John Brecking was and is wonderful and I met up Sam Todd and Matt Young who went out of their way to meet me. Brin was also there and we had a catch up.

The worstestist thing was the match - Wycombe at home

It isn't for everyone but I would recomend that if you can afford to treat yourself then do so once. You may like it more than you think.
