Hi, congratulations, you get to meet your baby soon 
I had my DS in Simpson's 4 weeks ago, I was also induced, and I can reassure you that we received excellent care.
I wasn't on the ward to begin with, I was already dilated so was induced in a labour room, then moved up to the ward after ds was born and we were delighted with how well we were looked after in both places.
The labour rooms are functional, not beautiful, but if you need a birthing ball, floor mats etc then you just need to let them know. We had a pool room but those without have a big wet room. I took some electric candles, iPad loaded with films/music , my own pillow etc which helped make it more comfortable.
We had one change of midwife during labour, but both were lovely.
You'll still be able to move around if you have the drip, it's just a bit more awkward.
Basically I would say that it sounds like you were feeling how I was feeling just a few Saturdays ago (I also went in on Monday) and I can reassure you that the staff are great, the ward and rooms were clean, and the care was excellent.
If you haven't done it already, I would recommend writing out your birth preferences and any specific questions you might have so that you can talk everything through on Monday - I had tons of questions, apparently no question is too daft to be asked!!
Feel free to pm me if you have any other questions I can help with and good luck!
