Travelling, whether it's to a far off country or just up the road needs to be comfortable. We have all heard of first class and business class but what exactly is luxury travel on a coach? There are different types of coaches for a start. You can get a standard mini bus, designed to hold more people than a car. Then you have the standard size coach, these usually hold about 50 passengers. Next is the double decker coach, it has two levels and can hold between 80 and 90 passengers.
