Bedtime on holiday?

How are you handling bedtime on holiday? We have 4 long weekends planned this summer with family. Baby is currently 13 months. He currently goes down between 7:45-8:45 and wakes 2-3x nightly. Up for the day between 7-8. Last summer he just slept whenever, because he was a newborn. Regardless, our kid is super chill, will let anyone take care of him, and low sleep needs . So how do you do bedtime? Do you let them stay up and fall asleep when they are ready, do you follow normal routines? Do you plan a night for someone to put them down?
