I was induced recently at 41+1 as my bp rose and she was still not fully engaged so it was decided rather than give it any extra time we would induce. The gel didn't do much for me, and in the morning they were hesitant to break waters as she was still high up however 2 hours later the specialist decided she was in a good enough position (perhaps helped by my pacing for 2 hrs waiting to see if I was going to end up with a c section).
My labour was 4 hours from waters being broken and drip starting. I had read Birth Skills and planned to use walking, shower, fit ball, stress balls etc but didn't end up using most of it as I was on ctg whole time. I did however use feet movements on bed and focusing on breathing though the gas thing, the rattle really helped(only got to 30% gas). DH had a handheld fan on the back of my neck or face towards end too. I was able to kneel on bed with head over the back towards the end and I'm told that is a great position for pushing (only had 7 mins pushing stage though).
Obviously every persons labour is different, and how they experience it but just wanted to show even if it isn't the birth you visualized it doesn't mean you can't still use some of those skills you've learnt to help you through.
