Hope it's not Viking!
If it is Viking I'm sure you'll be safe but prepare to be delayed and if you are don't expect anything from them.
We were delayed for over 9 hours going to Corfu last week and they do not want to know. We had no refreshments and very little information.
The cabin crew were very nice though.
Now we can't find an address to complain to and the link on their web site doesn't work.
Good luck.
