I chose The Epic as this was my first cruise as a solo and I knew this was a ship that may cater for my needs. I was not disappointed as the Solo organiser was excellent and I met lots of lovely people. I couldn't get a studio cabin but had an inside which was more than satisfactory. The NCL staff on this ship were helpful and cheerful.
However 3 days before the end of the cruise they ran out of tea bags as they were not expecting so many Brits! A complaint resulted in chocolate covered strawberries and a bottle of wine (would have preferred a cup of tea!)
I investigated booking another cruise and was asked did I want to pay in dollars or pounds. The staff explained that booking in pounds meant I had to take the all inclusive price(drinks and tips) but if I paid in dollars or through a U.S. travel agent I could just book the cruise.For me it was a saving of £700 on the next one.So if you don't drink alcohol this information might be useful.
Cabin was clean and more than adequate for one.
