We are going to WDW for the first time ever in October, so we have no idea what it will be like once we are at the parks (even though we are doing tons of research). We are bringing my grandmother with us and she may need to use an ECV at times because her COPD and asthma wear her out. She is a big worrier, and I am concerned about her being able to load on a bus, monorail, etc. I don't want her panicking or anything like that. Can anyone give me tips to kind of help her out and make her more comfortable with the ECV? Thanks in advance!
