I was in a hotel after my breast surgery, lumpectomy with breast lift on both involving lots of sutures. I was 1/4 mile from the hospital clinic.
The one thing is, if I had gone home I would have been much further away from getting help if needed.
We made sure the hotel had a wheelchair on site, requested lots of extra pillows, and used hand sanitizer often. I usually bring my own pillowcases when I go to a hotel and put them over theirs, because I have sensitive skin.
If low BP is a concern, until you talk to the doctor, you might plan to have salty crackers on hand, extra drinking water, and plan how it would be easiest to raise your legs to move fluid to your body/head (lay on back, put 3 pillows under knees?). They should not discharge you until your BP has stabilized. I’ve had 2 friends whose BP was too low in recovery and they were kept for a couple of hours until all was okay. But planning for a later episode is a good idea.
Most likely extra pain med is just a higher dose of what they gave you, the clinic I was at dispensed it to me before I left after surgery. Anything more and you might have to go to a doctor anyway, whether you had been at home or in the hotel that would probably be the ER.

I felt pretty concerned about being in the hotel, but the alternative was driving 3 1/2 hours home over very bad bumpy roads, no thanks.
It worked out very well, though. The available room service is convenient if needed.
I hope your surgery goes well, and your hotel stay is uneventful!
