Vacation+rolling have ruined everything! Help!

My 6 month old was finally sleeping through the night consistently after sleep training with CIO at 4 months old. Well we went on vacation (3 hour flight and 1 hour time change) and things got bad. In a shared room with pack n play and slumber pod. First night slept well until 4am and then wouldn’t go back in crib. It’s just gotten worse and earlier wake ups since. And now she’s rolling on to tummy but can’t roll back and becomes upset unless she’s in a deep sleep (for naps and nights). We head home tomorrow and I’m wondering if I just do CIO again? We haven’t been able to here since my toddler is in the room with us. What about the rolling? If she’s screaming her head off on her stomach do I leave her there? I think she likes sleeping that way but just freaks out.
