I've read the FAQs and the multiple threads that discuss the on board booking of future cruises. We are sailing next week on the Wonder in a 1BR cabin. While we haven't sailed yet to see if we like it, I'm considering booking either the Wonder or Dream for next March and am pretty sure it'll be a 1BR again. But, it sounds like there isn't a discount for the concierge cabins and that those dates can't be moved without losing the deposit. Is this correct? If so, I see no benefit to me booking on board next week and should probably just wait until we get home, no?
