I agree with Brian and Gary about using the best doctors and facility if possilbe, but I had the convenience of driving 20 minutes from my home to MD Anderson and valet parking. Being in my home town I had my mom and sister and a host of volunteers if I ever did not feel like driving. While at MD Anderson I have met people from all over the country and the world for that matter, most of whom check into motels while they spend 6 weeks in radiation treatment.
In my opinion this is a luxury ( although a depressing luxury ) and obviously not everyone has the resources to go out of town for treatment.
In Desiree's situation it sounds like it would be very difficult for to travel all the way to NYC every day for treatment, especially with small children. You can only do what you are able to do.

My two cents,
