Part 5 and 22 are NOT possible without a tourist ticket as one portal isn't reachable without it. The last portal of a mission is often the first portal of the next mission slowing down the whole mosaic.
Other than that it is a nice mosaic that takes you to some very nice and scenic places in Cusco.
Great mosaic to see one of the most modern parts of Santiago. Great route setting with very little backtracking or repeating. Took me longer than expected as this is a great opportunity to build a lot of fields easily :)
The route setting for the first few tiles is great, but gets progressively worse. With the plaza on both sides of the modena blocked by police, you have to walk a lot more than those 5.7km to complete the mosaik because you get sent from one side of the building to the other and back repeatedly.
