Thanks Dave,

But, I seem to be confused.
I already have $600 SBC. If I book an excursion now, it's charged to my Credit Card. If I then cancel and rebook onboard, will the $69 price that was charged to the CC then be credited to my SBC?
I want to use the $600 I have already. Not accrue more SBC.
Am I missing something?
Thanks again,
J
