I have lymphedema in my right leg as a result of cancer-related surgery. I asked the lymphedema specialists at the hospital where I'm receiving treatment, and they had all kinds of good ideas for travel and WDW.
As you already know, air travel can be a trigger. Does your wife have a therapist? It might be a good idea to ask what additional precautions to take. Most of us aren't on our feet as much as we are at Disney and they might have some good ideas.
