I played a version of this game last weekend...went to the mountains with 8 friends and a dog!!
We managed to abandon one friend and a dog at check-in and rendezvoused nearly an hour later!
Another friend couldn't breath and/or slept almost the entire time and missed the activities and all of the meals!
Another friend couldn't partake of the hot springs because of a cast on her arm.
Another friend couldn't join us at the hot springs because of a risk of an infection.
Two friends had to leave in the middle of the night due to an emergency root canal need.
A seventh friend got lost and went 200 miles out of his way.
I managed to avoid any injury but stinging feet due to running after the dog barefoot in sand and snow.
Other than that, we all had a perfect time!!
