You don't mention that you are booked or not. If you are not booked I can say that not all tours are available on all sailings so the prices may differ or tours may not be listed. If you are booked and having a booking number consider creating a profile for yourself on Carnival.com and add your booking number. Once you've added the booking number you can see anything and everything about your cruise, which includes the shore excursions and prices. This will work for under 100 days out, but not for more than 100 days before sailing.
I am 84 days out for the Valor and I still don't have the full list. I saw a posting that stated that they are renewing contracts for tours offered and not all will be listed, which is a reasonable answer...I know what I want to do in Belize, Roatan, and Grand Cayman anyhow...Cozumel is nice, but I would rather just get off for an hour to shop and them get back on the ship to enjoy a fairly empty ship all to myself!!!!
