I'll be sailing "Paradise" again on 7/26. Already sailed her three times this year. Obviously, I think she's a great ship, and wonderful cruise.
Reference to your question. I haven't done that tour for a long, long time, but have heard others state that it makes a LONG, LONG day, even though some say it's a very interesting tour. Perhaps someone who has done that tour recently will chime in and give us more current information.
Be sure to leave the ship in good shape for me. Don't drink all the beer!
