Walk-Up: Zero problem.
During the worst of Omicron in Feb-March 2022, some worked offline, with regular clients only and 24H bookings...and strict health protocols,
like taking RAT test when they became common.
That was appreciated.
In some building, they were still operating normally with walk-in clients...I was not excited about it and passed.
Now it's NORMAL business. No worry.
Girls visiting your hotel should be NO problem....as if needed, they should have a BLUE Vaccination QR Code.
"Rules state I can't enter other hotels"
Fifty ways to apply those rules.
In Sept, I went to a Wanchai hotel photoshoot) with a lady:
They needed me to use LeaveHomeSafe to scan THEIR QR Code (found 1 Thai massage place that asked this too. Weird)
and to scan my BLUE Vaccination Record QR Code....which was no problem with my setup....but that would be a no for you.
But most short time hotels DON'T ask me anything when I take a room, just pay cash, no name.
In one hotel were there was a "nest" of ladies from a country north of China ...I was able to walk-up DIRECTLY to their rooms
(they were Amber Code then...so no house cleaning ~ chaos) without anybody asking me anything at all.
You can go to bars at MIDNIGHT (after updating LHS) on Day 3 (landing is Day 0) as your Vaccination Record QR Code turns BLUE,
but in the 24H before, you need to do a RAT test (you buy them at 7/11) , write name+date+time, take a picture of it and show it to the bar / restaurant you go to.
The pressure to relax some of those ....PERFECTLY INCONSISTENT (in 2020-2021, rules were making sense) rules is increasing big time....
but some in the government have REAL FACE ISSUES
and some of those rules are tied to Cap599 which requires Legco approval. Cumbersome.
In short, I don't see big headaches for you, with plenty of punting options.
