Glenda,
I received a response from the same company you mentioned advising me that they have an opening on the 17th for a sail and on the 18th a sunset sail. I did not tell them we were on the cruise.
I have sent more questions to them about where and cost,etc. I also have left a message for another sail/catamaran company that has a Newport Beach branch.

Is there anything else you would like to do while on the cruise?

I, too, use the wrist bands and eat the ginger candy placed in the ship's restaurants. I also have taken the ginger pills found in the vitamin shops. Inspite of what some say about the PG, you do need something for the motion. I wasn't sure about the band until one evening on the PG I noticed that there were not too many people in the restaurant and realized that the bands were working!
