I was just comparing suite sizes. Radisson vs. Crystal. There is a extra 100 sq ft in the lowest catogory. That's a lot of space to make your home in. Especially on a long cruise. The standrad balcony suite I was in was 256. That got a little small as time went on. 2 people would really have to be in love if you know what I mean.
That's what it would cost about $171,000 for me to do a full world cruise on Crystal all by myself by the way. When you add up all the extras. Rather drive a Ferrari
