It is possible to have a great UC in a hotel without a husband or partner. That's what I did with my son, my first (and only) child. I did have my sister with me, and my mom showed up for the birth as well.
I stayed at the hotel for two or three weeks before, I can't remember exactly. It was a pretty clean place even. One benefit to a hotel is unlimited hot water! And I kept the tv on when I was in labor to mask any noise, but I was pretty quiet until crowning.
What I really liked about my birth was how I took responsibility for myself and my son. I was calling the shots, and I found that to be so empowering. A great choice for me, but you need to decide what will be best for you. I'm sure it will be very reassuring for your parents to have a trained professional there, just make sure it will work for you as well.
I know it's cheesy, but listen to your heart, and do what feels right. If you are in labor, and don't want to call the midwife, then don't! Good luck and have a great birth!
