Hi there, I am sailing on the Solstice Sept 15 out of Seattle. I am sharing a cabin with 3 other ladies (I know!!) who are flying in same day and their flight isn’t scheduled to arrive until noon. I fly in on the 13th. When checking in, the app message says that our whole party ‘must board together (at the same time)’. It allowed me to select a10:30 boarding time and they selected later (1:30 I think). Will I be allowed to check in earlier on my own and will that create any problems for them? Anyone have personal experience with this?
