I spent a weekend in Liverpool recently and would recommend it as a city trip as there is so much to see and do. My hotel was beside the Albert Dock which is breathtaking. The area has loads of restaurants, pubs, etc and is brimming with life. For Beatles fans, I would suggest the Magical Mystery tour which visits all the Beatles' houses and culminates in a trip to the Cavern Club. Museum wise, there is plenty to choose from, the Tate Gallery to the Maritime Museum to the Museum of Liverpool. The best thing is they are all free!
