I was booked on this years cruise too, however I am due to give birth two days before it leaves so I was hoping for an amazing itinerary again in 2016 but I am really disappointed, I really wanted them to go back to Iceland etc as part of this cruise, for me Liverpool etc have no appeal, If it is an amazing deal we may give it a go but I just begrudge paying Cruise Line prices to get somewhere that I could go in 20 mins from home.
I also think that of all the places in the UK to Visit that Liverpool and Newcastle are not the best and will not give the best impression of how wonderful England is.
