I went in for induction on Monday 1st at 39+2.
The induction process and policy re in vs outpatient may vary by trust and the reason for induction, but I was admitted.
I went on to an antenatal ward so no babies, just pregnant ladies. 4 beds per bay, mostly all occupied all the time. I second pp who suggested eye mask and ear plugs. I suffered a night next to the worlds loudest snorer; kept me awake despite the ear plugs! Everyone was relieved when she went into labour at 2am so we could get some sleep.
Induction itself was via a pessery which is inserted behind the cervix to help it ripen and left for 24 hours. Ask for g&a for the internals as they can be uncomfortable, particularly if your cervix is unfavourable and posterior. Also you may need several internals which gets quite sore.
After 24 hours another internal where they'll break waters if possible. If not the pessary is left for a further 8 hours followed by another internal and waters broken if possible. If not they rest you for 24 hours. Another internal, break waters if poss, if not another pessery for up to 24 hours. Another internal and they will have a go at breaking your waters regardless of how favourable or otherwise (unless of course your cervix is still fully closed but that would be unlikely).
At any point in the above your waters may go spontaneously (mine did on day 3, 11 hours after the second pessery).
The drip may or may not be required depending on how you're progressing. I was lucky and didn't need it once waters broke. DD was born 19 hours after my waters went.
Induction does increase the chances that you'll need further intervention down the line but I managed a normal vaginal birth with just g&a, a tens machine and a shot of pethadine (which was useless IMO; it didn't ease the contraction pain, just sent me to sleep in between and meant they made me stay on the bed until it wore off).
DP and any children were allowed to be with me from 9:30am - 9:30pm. I sent him home a couple of days though as it was quite dull and he was more useful getting things ready at home. Others could visit 7pm-8pm, but only 2 people at a time (plus DP and kids).
Take lots of entertainment to keep you occupied if you can. I mainly bounced on a ball reading in the day and DP and I watched a film on the iPad in the evenings. You'll be able to go for a walk but not leave the hospital grounds.
It wasn't too bad (even the food was tolerable IME, just served at odd times - 5pm dinner for example) just pretty frustrating waiting 3 days (and DP using 3 days pat lave before DD even arrived), especially since everyone else seemed to come in, have a pessery inserted and immediately go into labour! DD was totally worth it though
.
Good luck.
