The WIFI at the parks is just as strong as at the resorts. Even if you could turn off the room WIFI you also has guest WIFI which services outside the rooms and can be picked up in the rooms as well... I would suggest you rethink your trip if WIFI is that much of an issue as I don't think she will be able to avoid it anywhere in the Disney parks or resorts or airports for that fact.... and now any house that are near that has cable will have a free hotspot for the cable company... Maybe it is not the WIFI and something to do with the electronics as all electronics emit sound waves as well... In this day I truly do not see how she would not have a headache 24/7 if it was WIFI or Cell phone bands causing this. I would try other Doctors to find a solution as this will only get worse.
