Just came across your post. Know it's old but on the chance you're still interested am replying.
I'm booked on HAL Rotterdam, Jan 9, 2013 on a 90 day cruise from Rotterdam to Rotterdam Cat EE. Would consider upgrading to a balcony if you're interested and I'm not paying the single supplement. I'm 64 GWM in good shape neat, considerate, easy going, don't smoke occassionally lite drinker who really like cruises and long ones are better. Let me know if you're interested. Last year cruised Rome to SanDiego via Lima. Had a cabinmate part of the trip that worked out well.
