I am in the process of planning a 2 week Disney vacation for next Aug 2015. There is a chance that a friend might be joining us who suffers from this. He has already lost most of the hearing in one ear but the worst thing is the vertigo. It comes on suddenly and severely to the point of him having to vomit and/or sit down for a bit until it passes. Some days he may not get symptoms and others have 3-4 episodes. Needless to say, the vomiting part is quite embarrassing to him especially in front of large crowds and tight spaces. I have told him about the DAS but since I am not even sure he would qualify I figured I would ask here so that at least he knows to prepare himself accordingly. Thanks for any insight as we have never travelled with anyone who is disabled.
