You will especially experience this if you go to the breakfast on the first few days. The Captains Club host doesn’t know all of the eligible members by sight yet, so you are asked to show your Sea pass card. If it doesn’t say elite or higher, you will be politely told that the event is not for you. Otherwise, the host would have to look up everyone’s names to determine who can attend. It’s much easier to have the Captains Club level shown on the seat pass card.
And just to be clear, you are not required to attend that breakfast but if you choose to it’s a nice way to start your morning
