Since 2012, my husband Patrick and I have traveled to 21 countries together. I use an electric scooter for mobility and a ventilator for breathing, and Patrick, who is nondisabled, is flexible and supportive. We prefer adventuresome and authentic travel experiences, so we have stayed in people’s homes from Tahiti to Iceland to Greece, that are offered through peer-to-peer lodging websites like Airbnb, VRBO, HomeAway, FlipKey and HomeExchange.
