Cancelling excursion booked with OBC

[mamax2]

Hello everyone,

 

I searched but could only find threads on booking with OBC.  

 

Booked the Aqua Trax excursion at Half Moon Cay for 9am.  Wanted to book a clamshell but it wouldn't let me stating conflict with another excursion as it shows a time for the clamshells at 9am.   I booked the first excursion with OBC (my cruise is after March 15) so it gave me the option to use the OBC we had.  There are other times for the jet skis at 11 so my question is....If I cancel the Aqua Trax excursion to rebook at the later time will the onboard credit go back on my account? Has anyone done that yet since the using of OBC to pre book excursions is still new.

 

I emailed shoreexcursions@carnival.com to ask but haven't heard back from them yet.
