Last year my husband was diagnosed with brain cancer (GBM). The prognosis is one to three years. In an effort to help us make some lasting memories, some friends of ours are sending us to WDW the week before Christmas. We will be staying at a time share that is closer to Universal than Disney so afternoon naps may be out. We have one 11yr old daughter who is very excited about the whole experience. I wanted to know if there would be any benefit for us to get a Guest Assistance Card. My husband has had radiation, two surgerys and is on an oral Chemo every other week that makes him very tired. A few years ago he would have been dragging us around the park, but now he doesn't have the stamina to handle long lines for hours on end. So far he seems to be okay with walking and we have already begun walking each morning to build up our leg muscles. A friend suggested we get a note from his doctor and get a GAC. How would that help us exactly?
