There was a particular concierge who did all my bookings, but I don't think I should list her email here. DM me if you don't get a response from that general email. It did take a couple days to get a response (before I arrived).

Also, there is an app / site that does work to e.g. change times. https://cunhi-webapp.hilton.goguest.cloud - If I recall, you set up a password etc.
