I've had two of my four labours induced, 3rd and 4th, both from being not very favourable at 38 weeks with twins and 37 weeks, and found them both positive experiences. I was lucky, one labour established fully within 10 hours and one within 8 hours.
My first induction with twins was much more intense pain wise, as I found kicked in very quickly and more intensely, rather than a slower build up with the pain and this seems common. They were also short though they were 3rd and 4th labours which made a difference, but intense and quick beats longer and milder any day of the week for me. I have a high pain threshold and am quite calm in labour and go into my own world, which really helps me cope and channel my energy. I managed with gas and air, but they will help you with pain relief and reassure you if you are feeling anxious. My last induction was better pain wise.
Re your DH staying, this would probably be dependent on what room/facilities they've got, but phone the senior midwife there to discuss it beforehand and hopefully get some reassurance. My Dh was allowed to stay quietly with me, it wasn't an issue, depending on monitoring you can also wander off to the cafe etc at times, maybe have a bath if no one's using etc, watch TV or read and then try and settle down and rest even if you don't sleep particularly well, but try not to let this worry you.
They can give you something to relax you and help you sleep. I don't sleep well in hospital either and have spent a lot of time in them due to general health issues and pg complications, I was given something last time, my labour started quite quickly, but I managed to get some rest. I had sent my DH home when it got later though so he could also try and rest as I thought it wouldn't get going till the next morning, he had to do a quick dash back!
You can also take a booklight, borrow/take a kindle, or use your wall light turned away with your curtains around, you can listen to some favourite music with earphones -try not to be too anxious about these issues, it'll be fine. In one of my stays they gave me an (electric) essential oil burner with lavender.
In four complicated pregnancies and many stays in hospital including weeks on the maternity ward with complications, I've had many different personalities of midwife, but never a 'thug'. I'm pleased to say mine have all been efficient and professional and extremely busy, but mostly kind and caring. If you don't feel listened to though, don't be afraid to be firm and voice your issues.
This might all be academic anyway as it might all happen beforehand.
Sorry it's a long reply 
I wanted to try and reassure you. Good luck.
