Wow, Carmen, I am so jealous!! I've been dying to go on a cruise but it's hard (almost impossible) to get on as a single without paying twice the price! P&O seems to be the only company that can do it.
I went on P&O's Pacific Sky back in 2001 and had an absolute ball! I went as a single in a four berth cabin. I got in with a group of really cool people, and I think we averaged about 2-3 hours sleep per night
It was a time to remember! And I'm still friends with one of the guys I met onboard - he lives just around the corner from me now.
Hope you have a really great time
