I tried also but I kept getting kicked back too. I called Carnival and they said they are still working on it and you cannot yet order excursions on line. You still have to book them on the ship for right now.

All, I have been told that online booking applies ONLY to the Triumph and Fascination and applies to booking later next month. They are starting to actually impliment the system now and they should hopefully have all ships and dates up and running in a few weeks. Noting 'Official" has come out from CCL yet but this is what my friends there have told me.
I received an email from Carnival stating that the Jan 8th sailing on the Triumph and the Jan 10 sailing on the Fasination were test sailings for online ordering of shore excursions. I haven't ordered any tours yet so don't know if it works.

It's funny that Carnival is having so much trouble getting their online shore excursions up and running. Particularly odd since Princess and HAL (both Carnival Corp companies) have been doing it for so long.
