Hi! I haven't been on a Windjammer cruise, but my parents did -- and I'm a travel agent.
People who enjoy Windjammer cruises are the same type of people who gladly trade luxury and comfort for off-the-beaten-path adventure and excitement. The ships are small enough to get into almost any port, so they avoid all the mega-liners.
You're not going to have the five star meals, plush cabins, swimming pools, or casinos. If you get seasick easily, or have physical problems -- this might not be for you.
I understand that some of the passengers become good friends, and there's a lot of late night partying. You may be asked to help run the ship, or help load food & drink .
If you're like me -- this doesn't sound like much of an inconvenience at all! Go for it!!
