Sorry no idea either. I just paid up for a nice suite for a 1 week mediterranean cruise as my honeymoon in july. Can't wait.
..I've been on plenty of 'cruises' between Helsinki and Tallinn, and between Helsinki and Stockholm..but thoese aren't really 'cruises' as you know them.. they're more like a drinking-fucking-fighting-puking-endingupinlockup kinda things.
