1yr old transitioning to 1 nap

so about a month or 2 ago my daughter tramsitioned to one nap. it took about 2 weeks to fully transition. but now shes going back to 2 naps. shes beens walking since 10 and a half months and will be 1 on march 26th. shr just popped out a new tooth and looks like there more on the way. do u think maybe she just transitioned too early, or its caused by teething? she seems to be over the pain of the tooth thats in. ans were going on vacation this weekend to visit family. should i try to keep it 2 naps while were gone? because i know everyone will want to play with her all the time, and she will not want to nap either. any help is appreciated! thank you!
