We got the REF $50 credit for our recent Wonder cruise.
Just for giggles, I went to Guest Services on Monday night to verify that our credit was on the account. It was not.
They were very helpful and promised to call CRO the next day to research the credit. Very early the next morning, I received a phone call to tell me that I indeed had a credit and that my account would be adjusted immediately.
Later that day, I recieved a call confirming that the credit had been applied.
