One member of our party of 4 bailed-must be reading the bad reviews!

I was cruising with Carnival Liberty two months ago and am considering having another cruise again but would prefer having a cruise with another company. I am not that much familiar with what are the basic behaving rules while on board but it is just that it has happened on this cruising that one member of our party of 4 bailed though I bet he must be reading the bad reviews?
Anyway I was Caribbean cruising and though it was my first cruise I loved it despite this 4 bailed situation so I would like someone suggest me another cruise company I would like having some Europe cruising.

There you may find many good reviews on cruising with Costa line which is purchased by the Carnival few years ago by the way but are functioning just great and the ships are perfect and so Italian in style. I was cruising with those ships for more than 5 times and I always had perfect parties there without any inconveniences. Anyway I have booked a cruise with Costa Mediterranea for this summer and it would be Western Mediterranean cruise about and I bet it would be great so I suggest you consider booking some of those Costa cruises for they cover all Europe and its cruise offer is very wide.
