Where did you hear the check in process changed? My understanding is that it is still the same, and at the same location. I imagine the ability to select your table number may change from CM to CM.
I am not sure when you are going, but we are doing this on Sunday, and I can report back.
Edited to add...I forgot reading about a mobile check in option a few weeks ago. I will definitely provide feedback if that is the case. Sounds preferable than having to wait for the wristband and then again for the seats.
