We did one cruise on Balmoral s few years ago (a very good price tempted us) and we had a great time, although we were the youngest pair by about 20 years!
I quite often look at the FO cruises leaving from Liverpool, which would be quite convenient for us, but the prices are very very high, coupled with the fact that the balconies are mainly terraced balconies on Borealis. I can’t justify the additional expense.
