I looked into doing this on my last trip but since I was there for only 6 days and most of those were Holiday's it didn't work out.
One idea I did have which I might try this next trip is renting a car yourself, then possibly hiring someone to just come along that knows the way? Or if you know anyone there that would go along, unless you don't feel comfortable driving. I wouldn't mind driving as long as someone else was with me that knew the way and could remind me to stay on the LEFT side of the road. lol.
