We bring our own blankets (me and the kids, DH thinks we are nuts) and pillow cases. I am a total germaphob when it comes to hotels. I request they change the linens and then I put our own pillowcases over the new clean ones housekeeping puts on and we ALWAYs bring our own blankets. I bring lysol wipes and spray to clean the door handles, remote, phone, toilet seat, handle, faucet handles, etc...you get the picture.
DH thinks I am NUTS, and with us flying to Disney, he had concerns of packing our blankets, he actually said this to me the other day, You know, you cannot bring your blanket to Disney, right. And I was like, Heck yeah, I am bringing it and I am bringing the boys blankets too. Of course he is concerned with having too much luggage. I told him I will make it work.
