This is what I did. I live in Phila and traveled to LA with my husband and son to have my AN removed Aug, 2015. I found a house to rent outside LA instead of staying in a hotel. LA was too expensive so I found a great house in Pasadena and my husband/son traveled to visit me in the hospital. Much cheaper and more comfortable. Go on VRBO. That's where I found it. Don't worry so much about someone staying with you in the hospital. You will be too out of it anyway. Take pain meds often and the best piece of advice I can give you is to use an ICE PACK on your head in the hospital. It helped sooooo much and you won't need as much pain medication. The hospital probably won't automatically give you one, so ask for one. If they don't have one, tell them to make one by putting ice in a glove, etc. (I'm a nurse so we can make ice packs out of anything). Keep it on constantly. I slept with an ice pack on my head for several months afterward. It was my best friend.
You will need someone to take care of you after you're discharged. You will feel terrible and will need someone to be close by right after you get out of the hospital to make sure you don't fall down in the shower, etc. You won't need someone with you all the time.
Good luck.
