wow, we took our then 19 month old in 2017 and she didn't get into anything. Didn't care about the phone and never opened any fridges or doors or anything. She was more interested in playing with her toys. Just keep the patio or balcony door locked if you have one and don't stress about it at all. We didn't use the pack n play, she slept in the bed with us that trip and it was nice to have the extra floor space.
