Thank you for all the responses. Upon further review, here is what Viking sent me when they gave us shipboard credits due to a change in the itinerary.
”We hope you will find this change acceptable, and as a token of our appreciation for your understanding, we are providing you with a shipboard credit of $250 per guest—which can be applied toward optional shore excursions, spa services, Silver Spirits Beverage Package or any other onboard purchases.”
I will have to call to make sure I can use the shipboard credits for excursions as they are not showing up in MVJ payments.
