I had a similar situation last year when I traveled with a group of 18 people. At first, I thought a minibus would be enough, but honestly, it felt a bit cramped after a few hours on the road. The space for bags was also limited. We decided to switch to a full-size bus for the next part of the trip, and it was a game changer. More space, more comfort, and people could actually move around. If you’re doing long trips, I’d say a full-size bus is worth it. When we were in Düsseldorf, we used dusseldorf italy and booked a full-size bus. It wasn’t as expensive as I thought, and the whole group appreciated the extra space. If it’s a short trip, a minibus might be fine, but for anything over a few hours, I’d recommend going bigger.
