Hahaha, you should have brought the sausage butt and taught the kids the game called "russian roulette' snake style!! :D
"Alright kids, the game is you all line up and each of you takes a turn at putting the tip of the snake tail to your forehead for 10 secs" lol.
And to the OP, like mentioned, i would probably just bring one. Your most trusted one. A snake is a snake and can and will do weird and unpredictable stuff. Rosey who i have had for over 5 years as a baby and never so much as hissed at people and even sat there while the vet stuck a needle in the lump on her nose, did tag my arm when i startled her when i assume she was sleeping in the front of her cage. Things can happen, they are snakes.
