Tourists don't disappear, except for returning to the pier. The "bubble" is much more visible than the actual tourist. The bubbles appear and disappear (if not actioned) after a length of time, and so you will see the bubble disappearing at random places, which can often be over a green square. But if you switch to Grid View, you will see the actual tourist is still walking (unless he walked into the pier).

Tourists do not even walk to the end of a road (unless the road terminates on a green square). Tourists' routes are determined when they step off the pier. They are pre-determined to walk to some structure or other they can reach (green square) by the road. So you watch one tourist in grid mode intently, he will take the shortest road to that green square, and then turn around and go on to his next destination by the shortest route, hit that green square and turn around, before heading back to the ship by the shortest direct route. A road that extends beyond a green square never gets walked on. Unless their pre-ordained path is to go for a walk on the beach or a swim or a stroll on some grass. The main point here is two-fold - they don't walk to the ends of the road anyway, their bubbles just disappear at a random location; and secondly, given their path is pre-ordained coming off the ship, they will stick to that path until returning to the ship no matter what construction work goes on. Even if you delete a path and move a building onto that space, they will still walk through that space. ie. through the middle of your building. It can appear as if they're disappearing inside, but in grid view you can just see them walking their pre-ordained path, even if they have to walk through brick and mortar.
