The pick-up from one of the Valletta hotels was timely, and the trip to the ferry in a minivan was ok. Were given wristbands before boarding the ferry, and a person on the Gozo side would put us in small vehicles to take to the garage where quads were stored. Pics of Driver's ID were taken and short instructions were given. In particular, we were asked to follow each other closely in a convoy - which is what caused the problem later. The leader of the group (our guide who was in the front on his own quad) was braking unexpectedly before turns, and, expectedly, that led to some trouble. At one point he applied emergency braking as he abruptly decided to turn right, and sure enough, the rest of us (about 10 quads overall) couldn't quite follow the sudden move - being so close behind in a single line. Two ladies bumped into each other pretty hard, damaging both quads. For the next 40 minutes, we were all sitting still under the scorching sun while the tour leaders were trying to persuade the ladies that it was their fault and that they had to pay for the damages (I am not sure how it all ended with them). Eventually, we were asked to take extra passengers on the remaining quads, since those two vehicles were non-operational. That situation certainly spoiled the impression.
Another disappointment was the lunch (included in the price) - rather dry and unappetizing pasta with cheese and a glass of water. I am sure that the organizers could have charged an extra 10 euros per person (if money was the issue) but to serve something more appealing than that.
Stops were amazing, we explored Gozo from all sides. Not much 'touristy' information was given by the guides, though. Yet, the views were surely stunning without any additional commentaries. The trip from the quad garage back to the ferry was an experience of its own - seven people were squeezed into a tiny space of an old pick-up truck-turned-passenger-car. Luckily, the trip to the ferry was short.
Overall, the natural beauty of Gozo and the sea that we beheld partly compensated for other shortcomings of the organizers, but there is certainly plenty of room for improvement here.
