From my perspective:
I want automated check-in everywhere. Most of my trips are solo with no checked bags, and I'm a low-drama traveler. Ideally I would be able to go straight to my room and unlock it with my app.
If they need to verify identity, there could be a kiosk to scan ID and take a photo (or just a CLEAR kiosk similar to airports, as some sports stadiums have). It could be set up so that I wouldn't be told my room number and my app wouldn't be able to unlock any room in the hotel unless I finish the kiosk part.
I don't mind ordering food delivery on UberEats or whatever. It's simple enough and we're used to it (at least domestically). Going to street to get the food doesn't bother me, I have to do that in my condo building as well.
I do like hotel bars.
I don't understand the concern on safety and MAGC. They could still enter the room and quickly inspect it to make sure I'm not doing anything crazy, without cleaning it? It would take 60 seconds tops for most rooms.
There is no safety concern for MAGC ... it's made up.
as for your other concerns, UNITE Here does not want you to have those options so the organizers have persuaded people to strike. Turnover in hotels is significant so any technological improvements will easily be handled through attrition and wont impact current employee. It could, however, impact the total number of employees so there wouldn't be as many new employees paying initiation fees or dues to the union. Curiously, when the SF Council had their hearings, they didnt ask union leaders if they were manipulating members or why they were opposed to innovation
