What garage is closer to the Edison restaurant

Orange is a bit easier, the distance is about the same.

I recommend parking on the Orange garage

It's almost perfectly situated between Orange and Lime garage but it's a quicker walk from Orange.

We used Orange and it was perfect

We parked at Lime and it worked out well too.

If you choose to park at downtown Disney any will work. It is just 1-2 minutes walk difference.
