Backstory: we have 10 mo b/g twins that up until last week were eating 2-3x overnight and waking up even more than that. we have coslept parts of the night with ds when he's had a particularly rough time overnight. they wouldn't always need a bottle to go back to sleep, but would want to be held and rocked. they have separate rooms at home, and are pretty good about sleeping through each others cries when separated.

Sleep training: we started the Sleep Sense stay in the room style training on Friday night, and night weaned in the process. it's going really well. kids are napping longer, dd started sttn on night 2, and ds on night 4. they still wake up and squak sometimes, but typically put themselves back to sleep within 5 minutes. Hallelujah!

So, camping: We're going camping for the holiday weekend during nights 8-9 of the program, and I totally understand that it's going to stall us or set us back a bit, but I'm hoping to minimize the damage. This is where I need help

We have a small camper but it won't fit two packnplays. I'm not too worried about naps as we should be able to do decent naps between the car, stroller, and ergo. But at night, we've been planning to cosleep- DH to take one and a baby, and I'd take one and a baby. As nervous as I am about cosleeping, it seems like it it might be less detrimental to our sleep training to just cosleep from the getgo all night, than to confuse them by trying to put them in a packnplay, having them yell, and THEN cosleeping.

So, my questions:
1) has anyone coslept while traveling after sleep training? how did it go?
2) can you think of any other option besides cosleeping that we could try overnight? another type of travel bed?
3) what might be a good way to get them down for the night that keeps the idea of involving us the least? I was thinking maybe take a walk with the ergos or the stroller if they would stand it.
4) any other advice for camping with older infants?

I know this is kind of a weird situation, but any ideas would be much appreciated. Thank you!!!
