not OP but have been on two sailings. If you google it you'll find 37-60 which sounds about right to me. A lot of the marketing made it sound like the boat would be choked with influencers but it hasn't seemed like that to me. It doesn't feel appreciably different from any RCCL sailings I've done (other than the kiddos)
I had it done at the port for my NYE cruise, and it's possible something has changed since then, but I don't remember it being particularly invasive like that. Just a normal swabbing.
