We booked a cruise for April on Arvia, whilst on a crusie end of July.
We only had to pay £100 deposit so no great fuss if we dont go, oe as others have said we can look at the price when we have to pay balance.
We also got £880 OBC
1st time we have done this but looked a good deal to me, it appears that this cruise was the 'special offer' as they were a lot of takers at the time
