I met my wife while sailing on SS Canberra some 19 years ago. Now, after 16 wonderful years of marriage we have decided it's time to introduce the kids to cruising. We will be on the Mariner in a Grand Suite in May and will be traveling with a 14 year old and an 11 year old, as well as with my father who will be in a promenade cabin.
My question(s) are regarding the concierge room for pre-dinner drinks, can we invite my father in as our guest, or if the kids are excluded during those hours could he use one of their keys to get access? If we have priority boarding for instance would he be able to board with us a group or should we all stay together and board at the normal time?
