I am loathed to check-in (or out) downstairs on level 2. Wherever possible ask (or accept) a lounge check-in on level 31.
The priority line is rarely policed / used as it should be, and the staff downstairs just don't know what they are doing. They seem to regularly give out rooms pre-allocated for Diamonds to other guests, then give Diamonds inferior rooms, they forget to add late check-out, they forget to ask / apply the diamond amenity, and the list goes on.
The lounge staff are generally okay, and Mona is really good at trying to be accommodating with the hand she is dealt.
I know a lot of staff at this property are just starting their career in the hotel industry, but it really shows sometimes. They could do better with supervision and/or training to avoid regular screw ups.
