What to do in Berkhamsted in this horrible weather?

We've got people coming to stay for the weekend and I can barely see out of my window for the wind and rain! Our plan for some nice canal walks doesn't seem too appealing now! What else is there to do with guests in and around Berko in this weather? Any tips for where to go?

Grab some Monopoly, Scrabble and whatever else suits your fancy, get your friends round, order pizza and fill the house with booze. Job done for the weekend ;)
