Long story short (and I’m sorry if you already know all of this) - traditionally Disney suites are CL access. Later last summer a bit after reopening, Disney decided to make the suites across all the resorts bookable but “took them out of the CL category” since at the time there was no clarity on the return of CL. Note the rates did not change.
So fast forward to now where we have reopening dates for some CLs, we’re in the somewhat weird situation where several of us like yourself have suite reservations for a date for after CL reopens, but the reservation detail still doesn’t say CL.
I’m assuming that’s more Disney website/booking technology related more than anything - I’m guessing their system isn’t programmed/set up to have a bookable room category for some dates that are CL and some that aren’t, so they’ve just left it alone for the moment.
Plus there’s no physical way a suite guest in the main building could be excluded from CL services anyway, and it would make very little sense (in my opinion) for Disney to even attempt as such.
Sorry for the long winded answer - hope that helps!
