Go to the Windjammer part of the cruise lines section above. Since not many people post there you only have to scroll down a few lines to find a five or six part , pretty detailed account , I wrote of our Windjammer cruise. Not on Poly and not a singles cruise ( About half singles and half couples), but it will give you a flavor of what this Windjammer thing is all about. As stated above you will either love ot or not, but I would do another again in a heartbeat. Speaking of that, I have run into the Poly in several ports and simply dreamed of a cruise on her each time we see her.
FYI our cruise was on Flying Cloud which has since been retired.
Make sure you do the stow away night, the party really begins that night.
