traveling by myself

The other day I went out to eat dinner with a friend, She'll be going to med school on Grand Cayman Island. She asked me if I would ever be interested in going down there to visit her, but that's something I could never do by myself. Once I did go visit a girlfriend that lived around Washington, DC, I flew up there by myself, but she was there to meet me at the gate, and we stayed at her house up there. She helped me with whatever I needed. But it would be pretty impossible to fly somewhere and get to a hotel by myself. I am unable to push myself in my wheelchair, and I couldn't handle the luggage. Even taking a bath or just getting around a hotel room is pretty impossible.
