Hey, guys!! I am new to this forum.........but childfree by choice!!

I am actually going to Disney with my bf and *lump in throat* my two preschool nieces and their parents......I love my nieces but they are prone to the following: screaming, yelling, throwing, biting, spitting, peeing, knocking over really expensive objects, running through restaurants and basically acting like that girl from the Exorcist (minus the head twisting, but with the projectile vomiting).........so I am hoping and praying (that is if I actually prayed) that this trip will go well. My sister and brother in law are pretty aware of how annoying their kids are and promise that they will be kept in the hotel room past noon *just kidding*. I am really looking forward to this trip and my bf and myself keep practicing meditation and deep breathing.........
A game that my bf and myself like to play when there is an annoying and crying child around is, "Guess what sucky job that kid will get when they are older....."
It goes something like this:
Spot crying, screaming, snotting 4-year-old from miles away.......get closer.....closer......almost go deaf..........then say, "She will be a
Walmart greeter!!" It makes us smile to know her destiny and lessens the pain from her screaming.
