From what I have read and seen,he must be able to walk thru the houses and get his ECV at the end.The houses are way to tight for anything but walking.
I don't know the ins&outs of it,this is only what I have seen personally.Someone will come along and correct if I am wrong.
I was thinking on the same lines as donaldduck352. I have seen people on line for the houses with an ECV, but I have never seen them in one of the houses.. most of them are very tight spaces and not much room for even 2 people walking side by side.. usually single file.. for the most part.....
Actually...tonight I was behind a family who had a person in a wheelchair and they stayed in it the whole time. So while an ECV might be out, you apparently can use a wheelchair in the houses.
