I've had a number of surgeries with general anesthesia, and I think there were only two times that I woke up with a sore throat. They never intubated me while I was awake. Going into the surgery room was always a little scary, but at the hospital I go to they have a tape deck and their music tastes coincide with mine, which makes it easier. You might could ask them if they can play music when they bring you in, but it's only a few seconds to get transferred to the table and put under, so it might not be worth planning that part.
For me, recovery is always the bigger problem than the hospital experience. I always wish I had done more grocery shopping ahead of time, or pre-cooked more meals, or cleaned the house more. I try to remember to vacuum the day before surgery, and I get out whatever music I want handy for the next week or two. I put water and books near my bed. Minor things can be difficult right after surgery.
I've had trouble waking up. I've posted before about how I felt it was not cool that they discharged me while I was still disoriented, but I recently had a "duh" moment about that. My kid woke up during surgery once, and I'm intensely afraid of that happening. I talk about that to the doctors, so of course it's hard for me to wake up. They give me higher doses to make absolutely sure I don't wake at the wrong time. I'm okay with the trade-off and I guess I just need to make sure I have a sitter for that first day.
You can talk to your healthcare providers about any concerns you have. They can use medication to calm you as soon as you get there if that's something you're comfortable with. You will probably have an IV inserted right after you get an armband and your vitals checked, and then there's like 20 minutes of questions and double checking from various people, and where I go they put a heated blanket and inflatable anti-clot things on my legs no matter what kind of surgery I'm having. You get to meet almost everyone who is involved in your surgery, and you should be able to ask questions at any step in the process.
The experience of general anesthesia is like having time deleted from your existence, like an edit in a video. I've come to and tried to finish a sentence I started an hour before. You don't feel the discontinuity. Sometimes I wake up and don't believe that the surgery has already happened, and I think that's not uncommon.
