Some may find it a bit tacky but if you can avoid the kids, trying out the biggest rides at a theme park makes for a great day out. Throwing up is a big dating taboo, though, so don't drink too much then push yourselves too far. Blackpool Pleasure Beach's Pepsi Max Big One (once the biggest ride in the world) should provide sufficient excitement. Alton Towers in Staffordshire, with its verticaldrop Oblivion, is another good bet. Londoners can try Thorpe Park's Nemesis Inferno and, for the Scots, there is M&D's at Strathclyde Country Park.
