Might you be thinking of BookishPrincess? I think she travels with a guy who films her and she has short, brunette hair. She has many CL videos, though her information/wording isn't always accurate.
HERE is the link to her RPC lounge video and
HERE is the link to her room tour.
Because you're staying CL, even if you do OCI, you still have to be escorted up to CL because your MBs won't work in the elevator. Even if they did work and even if you got your room number texted to you, you can still "check-in" the old fashioned way even after doing OCI. Some resorts no longer have "Club Level Runners," and some resorts do. Sometimes they're busy and can't escort you and you'll have to stop at the front desk and tell them you've arrived for your RPC stay and you'd like to check-in upstairs and someone should then escort you. That's going to be my approach when I'm there next month.
