I have a question about buying CruiseNext certificates. During my last cruise in 2022, two CN certificates were offered for 500 USD with 250 USD OBC for using onboard spendings. I have two questions. First, what is the current price for CN certificates ? Second, must I obligatory use above OBC connected with CN during cruise ? Is it possible to pay only the difference, so 250 USD for 2 CN certificates ? Thank you for any help π
