I agree...in some cities the location wasn't the greatest..
Recently in Miami and Tampa, it was a $5 cab ride to the venue and there was a shuttle for those who weren't all that concerned with being in the GA line....which was pretty funny because I met some people who came to pick up their tickets and left while we were playing, and then after our set I jumped on the ETS bus with the others who wanted to stay and party and we ended up seeing the same people inside the ellipse...pretty cool..
In Ottawa the ETS party is a 4 minute drive from the U2 concert (under 2 km).
In Montreal, the parties are less than 1 km or 2 minutes driving, you would likely just want to walk it.
If you need any help with directions, shoot me a PM or email and I'd be glad to assist..
