So, I have nonrefundable hotel reservations because I purchased them through a travel site. Two weeks ago, my 14 year old kid gets a hairline fracture right below his knee. He is in a full length soft brace (as opposed to a cast), and he limps around the house without crutches. He can't bend his knee while wearing the brace. I really don't want him to walk the distances required in the parks, but he doesn't think he will be able to extend his knee while he rides the scooter. Also, he is concerned that it is a hassle to use it. What would you do in my situation?
