Just back from liverpool, this is our second shopping trip. Stayed for two nights but could easily be done as a day trip. Flight over at 7 45 am and back at 9 45pm. very short trip right into centre, city is very compact and shopping excellent. You could also do the beatles tour and visit the excellent free museums in the Albert dock area.
Have to say I never had any expectations of liverpool but it turned out to be really interesting and very beautiful city and the accent so nice.
