Sam, Welcome to our board!
There are several threads about
ECVs on our board - if you scroll down the front page you will find many good discussions.
We have some descriptions of accessibility of attractions which can be linked ffrom the DIS home page, or you can follow this link:
http://www.wdwinfo.com/wdwinfo/disabmain.htm
and be sure to look at the section about Mobility Disabilities.
Look at the disABILITIES FAQ - just click on the link in my signature. It is outdated now - I can't access the file to update the information - but the information there is still good. Please feel free to ask any specific questions!!!
And again, welcome!
