For me – Cardiff in the playoffs – ages since there was a local game to go to and need someone near(ish) to replace Portsmouth and Reading going down a few years back.
Though i can see lots wanting Blackpool and Forest for the day out.

As for Cardiff – I spent about 4 days there for our Carling Cup Final in 2006 & I thought the nightlife in the city centre was pish poor. Then again i may well have been too drunk to notice anything
