In this guide we will be covering the easiest way to get your 150 pinatas as quickly as possible. The path involves going through Lion's Arch for it's 35 Pinatas a little over four times over. You can do this by logging on one character and knock out the 35, then hop to another character and do this over and over again til it's done.
Alternatively, you can knock out 35 and run out to go handle the holograph projectors. Then return to Lion's Arch, knock out another 35 and do the projectors again. Repeat until you're done.
As you can see there is plenty to go through in a relatively straight line from the Trader's Forum Waypoint and all the way down to the ruined Signal Tower. Below will be an array of images for references in case you can't every single one starting from the top down to the bottom.
You can find the rest of Guild Wars 2 Hubs Dragon Bash content by hitting the Waypoint below!
