I had my twins by elective CS three and a half weeks ago and I've been astounded by how quickly I recovered/am recovering.
My twins were born at 10.30am and I went down to the ward at about 3pm. As others have said, you'll be completely bed-bound for the first day, partly because of the catheter you'll have in (on that point, please don't worry about the catheter like I did. They put it in after you're completely numb from the anesthetic, it doesn't hurt while it is in as it is a completely flexible rubber tube, and when they take it out (which I was dreading), it just feels like you're doing an enormous wee that you've been waiting ages to do! No problems at all 
). All the midwives were really helpful, responding promptly to the buzzer when I pressed it, and more than willing to lift the babies over to me, or take one for a cuddle while I tried to feed the other, help with feeding etc.
The following morning (policy is after 24 hours in my hospital) they take out your catheter and send you for a shower (with DH or a midwife to help). I have to say I thought they were mad - I felt there was no way I could walk down the bay to the bathroom, nevermind stand in a slippy shower and move about! I was wrong - it took forever to walk to the shower, and it was hard work to go through the motions of cleaning myself and removing the wound dressing (more later), but coming out of the shower, I felt like a new person . The walk back was so much easier, and they'd changed my bed while I was gone, so it was lovely to get in a clean be in my own clean nighty and be all clean .
The visiting hours in my hospital let partners be there virtually all day, just leaving for a few hours at mealtimes and for a rest hour in the afternoon. That meant that DH was there to help during the day (though the midwives were obviously there!) and then the midwives helped again at night. My babies were difficult to settle anywhere except on a person (didn't have to be me, any warm blodded being would do!), so a midwife took them to the nursery for me for a few hours (returning for feeding) on the second night.
I came home on the evening of day two as I felt perfectly fine (though moving slowly) and I knew my husband would look after me. This was absolutely the right time for me to go home, though I wish I could've gone back a few days later for some sleep and more breast feeding advice. Given my time again, I think I'd stay in despite wanting to go home, just to get that day 3/4 support, though of course there's no way to know you're going to need this until you've come home!
I have then recovered really fast. My husband was on paternity leave for two weeks, so did all the driving/fetching/carrying then, but before he went back to work , I got clearance to drive from my GP and insurance company, I then first drove at about 2 weeks + 2 days, with no problems at all. I have avoided lifting things purely because it'd be silly to lift things too early, rather than because I've not felt capable.
I still get tired and achy quickly. Can't walk for more than about 10 minutes without feeling it a bit later, but I was certainly fit enough to go for a short walk after about a week, and was moving freely around the house before then. As I said, I was really surprised at how quickly I recovered .
Sorry for the long post! I wanted to describe everything so you'll have an idea of what to expect.
Oh yes - removing the dressing! I was so so worried about this hurting, but it really didn't. The dressing is essentially like a large sanitary pad with a sheet of sticky over it. When you're in the shower, you get ti all completely wet, and then slowly peel it all off. I can honestly say that it hurt less then removing a plaster, and though I was reluctant to look at the scar, it was actually not too awful, and I found it helped to know what was there!
Hope this helps
