I went with my mom because I was nervous of going alone. Honestly, if you use the shuttle service they pick you up at the airport or the border and drive you to your hotel. By the way, they drove very well and not like a lot of other drivers down there. He will drop you off at your hotel and they will pick you up in the morning to go to the hospital. You really don't have to go anywhere alone if you don't want to. They will bring you back to the border or airport when needed. My mom and I were together the entire time and I felt very comfortable. I wouldn't recommend going shopping on your own though. I didn't do it, but I wouldn't suggest it. Overall, you are only alone at night when sleeping in your hotel and during the day when recovering.
