I travel solo a lot - both for pleasure and business. I often wonder about whether other people worry about the same goofy things I do. For example - when you are travelling alone - Do you always make sure someone knows the hotel you will be staying at? Do you call and 'check in' with someone from time to time during your trip? Do you worry you will fall off the face of the earth and they will be tracing your movements by your credit card purchases? In all seriousness, I do worry about those things. When travelling to Disney, I often don't know what hotel I'll be staying at (I stay offsite and make a lot of 'spur of the moment' trips), but I try to call and let someone know where I am once I do know. I also tell someone (a friend or my mom or sister) that I will call while away, and then check in every few days (depending on how long I'm away). Am I just paranoid, or is everyone like this?
