I would second (third, fourth, fifth?) the idea of looking into a food sensitivity, if she's arching her back a lot and still waking up that many times a night. As mentioned, the first things to cut out would usually be dairy and soy. That may not be it, but it's certainly worth a try.
As to whether or not that's CIO...Regardless of what anyone calls it, if you have to leave your house for the weekend because you can't tolerate the way your DH handles your daughter, it's probably NOT OKAY. By all means, take an evening or two if you feel overwhelmed, but don't take an evening or two just because you can't stand to be witness to what your husband is doing (or not doing) to your daughter. Besides, what do you suspect the long term outcome of ONE weekend of this will be? Do you really, truly, honestly think that will solve your problem? I haven't done it, but I can almost certainly guarantee you that it won't. My DH's sister did CIO with all of her 3 kids, and they all regularly cried at night. My neighbor did it with all 3 of hers, and I wasn't present for the first 2, but I know her 3rd one regularly cried at night, too. It seems to me that the more honest description of what happens is that it sometimes work and it often doesn't, but when it doesn't, parents just learn to ignore their kids when they cry. That's what we saw DH's sister do. They'd wake up and cry in the night and we'd tell her, only to have her say, "It's okay. She'll go back to sleep," without ever even going in to check. And she spent WEEKS doing the CIO routine with them, not two nights.
I *can* feel your pain about having a baby who doesn't want to go to sleep. My DD2 is very, very, very, very, very, very difficult to get to sleep. I honestly find it really annoying when people constantly say how it must be because they're overtired. (Sorry, whoever said that - you've just not had a baby like this, probably.) No, it's not just because they're overtired for some of these kids. Some babies fight sleep. It's nice to believe that you're a super-pro at knowing JUST the right moment to get them down to prevent crying due to exhaustion, but some kids fight sleep, no matter whether they're a little tired, not at all tired, very tired, etc. That's just what they do. My DD2 cried for 45 minutes tonight before falling asleep. (She's 6 months old, for reference.) She regularly cries for an extended time before falling asleep.
It's not even that I agree with people saying that you're supposed to try to comfort them, even when it's not working, because sometimes babies don't want to be comforted, however much other people insist that they always do. It's just that I think if you feel so bad about whatever's going on with your own daughter that you refuse to witness it, you are crossing a line that shouldn't be crossed. I actually HAVE put my daughter down on the bed and let her fuss until she stopped fussing and fell asleep. I did stay right with her, lie next to her, rub her back, etc., but I definitely let her cry until she was ready to sleep. She didn't feel abandoned. She wasn't crying because I stopped pacing, rocking, bouncing, nursing, jiggling, and whatever else I could think of that might soothe her. She was crying because she was tired and stressed out. That's it. Once she got it out, she fell asleep. That was actually how she fell asleep every night for a few weeks. Then that stopped working too. lol Now DH usually carries her around and she screams her head off for a while, then falls asleep within 10 minutes of him giving her back to me. She just needs to cry. I don't know why.
So I guess I'm not really helpful on whether you should or shouldn't do it. I just think that YOU clearly feel it's not right, which means it's not right for your situation. My DD got calmer and calmer as she cried. It sounds like your DD doesn't, which means it's probably a bad idea. If you search my old posts in this forum you should actually find one in which I talked about this and linked to some blog post someone put up on it.

my DS did the SAME THING the first 9 months or so of his life. I had to rock him and hold him while he screamed until he went to sleep. It was horrible.
He did have reflux and food allergy issues, but even with those sorted through, he was STILL a sleep fighter. He simply did NOT want to go to sleep. Then miraculously around 9 months old, he stopped fighting it. It partially coincided with when he started walking.. I "weaned" him from the rocking chair, first nighttime and then for naps. At night, I nursed him in bed, and then DH walked him around until he was asleep, and would lay him down in our bed. He didn't cry! Then I started nursing him down in the bed for naps, and he would actually go to sleep peacefully. We also dropped down to one nap a day around this time (10 months old) and I think that helped a lot.
