I just saw your post and was wondering if you had any luck finding someone for the May 18 cruise. Right now i'm in a predicament as i'm booked in an inside cabin on the May 27 departure (same cruise as you mentioned - 9 Day Princess). I paid $1204.98 for two (total with port fees and taxes) so not as great a deal as the one you found. But if you didn't end up going and you are interested, please let me know. I'm a quite, fun, straight, non-smoking late 30's female in Rochester NY - I'm driving down to Poughkeepsie the morning of May 27th and taking the train to NYC. Since i'm already stuck with this price (even if i go as a single) i could discount it down to what you had planned to pay for the 18th if you feel that would be fare.
Sorry - i didn't have time to set up my profile on this site as i wanted to write you quick.
Well if you did end up finding someone - you'd be leaving today. Have fun and let me know how it turned out.
