Good luck. My pre-op experience at the university of Iowa was similar. One IV before surgery. They wheel you away, ask a few questions (they asked me several times which side we were operating on). I saw the surgeon give a nod to the anesthesiologist and that was it. It's pretty surreal. But all the other parts of the surgery happen after you're out, from the catheter to the shaving of the hair, etc.
When I woke up I was super cold. I asked for my wife. But you're pretty out of it for a few days. Lots of nausea. I was in the hospital 5 nights, which I think is still fairly standard. Balance, strength, fatigue, are all difficult. But, when I awoke from surgery I also had this overwhelming sense of peace, like "it's over." I found the week leading up to the surgery almost more difficult.
Good luck! Feel free to reach out if you have more or more specific questions.
