Yes, now it is. First used CL as Diamond in 90's before there was a DL. First Diamond, now D+ have lost CL.
Cruises I'm on DL is never empty. So many Diamond's and D+ that along with DL they get Crown Lounge and 2 other Lounges to use 5-8pm... That said we've known was coming last 2+ yrs. First Diamonds, now D+ have lost the CL. Not surprised
