Well, to be honest I plan my trips very meticulously. Traveling solo is a challenge for anyone but especially more so when the person has limitations. I have been in incredibly unsafe situations due to my disability. For example, taking a hike I thought was easy but turns out it was incredibly strenuous and I almost fell to my death.
Generally, I have better common sense and stuff like that doesn't happen often, but that is why I have to do tons of research on the destinations I visit to make sure they are safe and they have activities I can do.
