Honestly, we thought using the buses was much easier. We only had 6 kids, 2 in strollers (2yo and 3yo), the last time we went. We also had friends w/ us who had 4 kids. So, 14 people total...10 were kids 2-13 yo. It was so much easier than getting everyone in the car, buckled in car seats, etc. We drove one day to MK and regretted it b/c it was so much trouble. When we went back that evening, we took the bus, as we did the rest of the trip. We kept our strollers folded, backpack on our back, kids ready to hop on the bus...while we were waiting. That way, when it got there, we just hopped right on it, very quickly without causing much congestion for those waiting for all 14 of us to board, lol.
