IDK if WBC has them, but just a suggestion that you bring your own. Our pharmacy offers a small travel size sharps bin (guessing 4*4*6), so we can have it along throughout the trip. DS is T1D and pops it in his suitcase; he travels all over for varsity track so it is very convenient. He might keep a couple of used sharps in his pen pouch until he can unload, but it is easier to have your own mini-container along. Disney does have sharps containers in most bathrooms, although they are often enough full to overflowing.
