I walked past this cache today when I only had about one hour left before I had to head back to the airport and continue the rest of my SAN-JFK-HEL-DUS trip. When I first approached the area, I thought the hiding spot would be similar to that of a cache at a similar location in Cologne, but looking at the cache properties, I quickly realized this was not the case. This really is an extremely muggle-y area and I doubt there is any time of day when there are less muggles around. So I resorted to the same trick I had already used earlier today: dump my carryon next to the cache location (thanks for the useful hint!) and pretend to search for something in the bag while grabbing the cache and putting it into the bag. This strategy worked really well - apparently nobody cared what I was doing. Kiitos for placing this nice cache, it's always nice to find a proper cache container (i.e., larger than a nano) in very touristy areas.
