I am at the TdI now and I also find it irritating how high the prices are for the Ventura / Tikariy tours from the hotel itself
As [MENTION=94033]Fizzer[/MENTION] said, I took taxidatum.com from CUZ to the hotel, stopping by Pisac Ruins / Pisac Market and an animal sanctuary for $65
For getting a local taxi to Olly - did you just go out front to the main street and barter / find one?
