For the non-physical bots, it would've made sense to have them "shadow" a human until they were equally or more capable and only then roll out a hotel with them

For the non-physical bots, it would've made sense to have them "shadow" a human until they were equally or more capable and only then roll out a hotel with them taking the helm. Things like reception desk Q&A could easily be integrated discretely, with the human employee getting help from the bot and overriding when it falls short. There is already a fair amount of automation for tasks like self check in at large economy hotel chains in the UK - and you can see how well it goes down with customers from the queues (which tend to favour waiting for the human assistants except at busy times)
