Half moon Cay water shuttle process -Carnival Sunshine?

[Thenagers]

Going to Half Moon next month on Sunshine.  We are there from 8-4.  What is the process for excursions for water shuttles?  We have a 9:15am excursion.  We also booked a clamshell and want to get that set up 1st?  Any pointers would be appreciated. We had Faster to Fun last time so this is different?

You will receive instructions with your excursion tickets.

Because you have booked an excursion you will be able to board an early water shuttle to HMC.  I believe clamshells are first come/ first served so I would go to the excursion shack on HMC and get your clamshell.  Remember that lunch is provided so you can hang out till the last water shuttle back to the ship.  Have fun!!

I don't know if you need to go to the excursion shack for the clamshells. You just trade in your ticket with one of the workers who unlocks the clamshell/sets it up.
