Half Moon Cay Excursions, Sensation in December

[cosmolulu1]

Hi - We've been to this island many times and always book a villa, which we love.  Since I have booked (back in June), there are no excursion options under this day at Half Moon Cay.  Carnival says they haven't posted them yet but this seems unusual, the cruise is 3 or so months away.  I did notice there is another Carnival owned ship at this stop on the same day.  Do you think they are just offering the excursions to the other ship?  It just seems so odd to me.  They typically list about 6 different types of choices like villa, cabana, horseback riding, sea life programs etc.  I do see plenty of excursion options for our two other ports - Grand Turk & Nassau.  The villas are limited so I just want to make sure I book one.  Any input?
