I made a reservation in specialty dining for myself and several friends on Sky Princess for a cruise that starts next Saturday. The reservation was made several weeks ago. I just found out that one of my friends is no longer able to go on the cruise at all due to health issues. He's cancelled his booking, but it still shows up as part of my SD reservation. Is there any way to remove him/cancel his reservation through the app, without having to cancel and re-book the whole thing? It's a fairly sizeable group, and I don't want to risk not being able to re-book at all if people book up the space before I can get the app to re-book the reservation. If I can't do this ahead of time, then I figured I'd just sort it out once I'm on board next Saturday. Thanks in advance for any help!
