Well it depends, if its used as going from point A to point B as part of another holiday its a big chunk out of your holiday allocation.
Believe it or not l actually considered thinking about including a January crossing to get home from America, but then from my point of view 7 or 8 nights is simply much too long to waste
on a crossing home.. when the time can be better spent within America.
To even consider a crossing cruise is something that surprised me, It didnt last long ,but the answer is No in my view. and for the foreseeable future that remains so.
Heck l remember it was possible to have holidays, zipping down to London, a crossing to NY, a day there, a crossing back home, more time in London and all within Two weeks. Then again it was QE2..... and it was quite some time ago. Progress and making money have a lot to answer for.
But consider the fact when you have fares as low as they are on some crossings are Carnival so strapped for cash that such savings are required.
