Catra, Just a suggestion, but you may want to contact Disney and explain your condition to them. They are experts in hospitality and may have suggestions and know things about how to negotiate the parks that you have not thought about. I did use the new motion sickness medication Bonine (OTC) and it did not make me as groggy as the Dramamine did. Another thing that I did was to check my luggage so I did not have to deal with it on plane changes or have to lift it into the overhead bins. I cost extra, but at least I didn't have to worry about it. I hope you have an amazing time with your Mom and enjoy all the magic of Disney. I have to admit that I am a teeny bit jealous!!! Lisa
