Last time, getting out of south London and crawling back two days later cost us 13 hours of the precious weekend. We have learnt that it is well worth getting the two-hour train to Abergavenny then splashing out on a 50-minute taxi. For any weekend away, constrained as you are by its shortness, I would argue that trains trump cars. Getting the train can save valuable time on a weekend break, says Huw Oliver GETTY IMAGESAnd brave the local buses. These days I might even suggest you haven’t done Cardiff unless you’ve bar-crawled around the Brewery Quarter and mainlined a kebab at 2am on Caroline Street, aka “Chippy Alley”; nor Bristol unless you’ve caught some obnoxious experimental music at the Arnolfini (arnolfini.org.uk) or the Cube (cubecinema.com); nor Cambridge unless you’ve mingled with the folk buffs at the Junction (junction.co.uk) or the Portland Arms (theportlandarms.co.uk).
