The excursion listing usually appears about seven to ten days or so before excursions become available for booking.

To get the listing, click on Find a Cruise and select the cruise you want. Then click on the name of a port other than the embarkation or disembarkation ports. This will take you to the Port & Excursion page for the selected port. If the excursion list has been released, you will see a link entitled, "Receive All Available Tours Via E-mail" right above the symbol for "Light Activity/Walking." Click on that link, supply your email address and the complete list and description of all excursions will be sent to you very shortly.

Dave was kind enough to enlighten me a while back. Could never remember so I copied and saved it in a Notes file that I could look up.
