Word of caution: my DH and I recently traveled on the Island Princess. Normally our accounts are combined, this time they weren't. I didn't think too much of it until I realized they charged the credit card for full outstanding balance on my account and left money in his to be turned over to Corporate Finance. There was $18 refundable and $21 non-refundable, I know they will quickly add both to Princess account. Not that large amount, but it could have been. I'll watch closer next time.
