I might be wrong, but I remember sky suites and Celebrity suites had limited access to Luminae in the beginning.
Luminae was introduced in April 2014. I dont remember how any months the access was limited, but it was. I want to say the limited access was less than a year.
Around the time X introduced Luminae we were doing 3 to 5 cruises a year, mostly in AquaClass. So I looked into suites.
