Give Route 6 A Bigger Bus

To the Minibus Executive Travel Company and Aldenham School,
We the undersigned feel strongly about one issue, that of the bus size of Route 6. Unlike every other bus, ours is about half the size of a normal coach, this causing problems.
Every morning and every afternoon we struggle up the tiny gangway unsuited to people with large bags (as we have) looking for a place to sit. Unsurprisingly, theyve all been taken. This results in bickering over seats and means that we are normally the last to go, resulting in lateness.
We have already spoken to two coach drivers and a company representative at the school about this. The representative flatly refused to negotiate, but one of the coach drivers (who has now since left) explained that it was easier to drive a small bus through the country lanes required to reach our school than a large one. However, that was last year and there are now more people. The other coach driver gave no explanation, but instead postulated that instead of placing our bags on the front two seats we put them in the coach boot highly unsatisfactory, as it only frees up two seats.
To illustrate an example of how sheerly overcrowded Route 6 is, last year an extra vehicle was required to take some of the pupils to school as the main one was full. There were fewer people then. If the administrations refuse to give us a bigger coach, this incident, which only happened once to my knowledge, may become routine.
Every other route has a normal-sized bus and manages rather finely. Is the Route 6 driver too inexperienced to handle one or something?
Our coach is small and utterly stuffed. Even if Aldenham School needs to hire another company (as it did for Route 2) or another driver, please let it be at that cost rather than the infinitely more precious cost of time and space.
