With suites sailing at full capacity, I don’t think exceptions should be made for non suite passengers, even in upper suites. Our last several cruises have shown lapses in service due to staffing issues. Adding additional passengers to an already full Luminae dining room is diminishing the suite experience that we have paid for.
I do realize that this is problematic to suite guests with family/friends traveling in other categories. We also have friends joining us for an Antarctica cruise who are not traveling in a suite. We plan to see them in lounges and on excursions. If they wanted the suite experience they would have paid for it. Why should we be subjected to longer waits and poorer service for passengers who failed to coordinate and plan well?
