My room attendant was almost apologetic when asking if I needed am or evening.I chose am as I always found I was always getting ready when twice a day. The only thing I asked was it possible to have an ice bucket in the evening, which was always delivered.
The facts are costs have increased world wide, so whilst cutting room service to once per day and therefore staff have more rooms to service makes some saving for RCG after increased labour cost. That is not the only reason I believe for this change. Since COVID there is also a shortage of workers.
