I have made the bookings. My question is more focused on making sure it's ok and Hilton won't do anything weird like check me out of Hotel 1 when I check in to Hotel 2.

I have a room in Sacramento for 6 nights, booked via corporate TA. I intend to go into San Francisco for 1 night (booked direct with points) in the middle of my 6 night Sacramento booking. I will then return to Sacramento and complete my stay.

Is this ok? Obviously both rooms are booked and paid for so I don't see why Hilton would care.
