any age can travel with Shearings, they do cater more for the older traveller who no longer wishes to drive themselves, hotels etc are of a decent standard.
The main bug bear is that they put you on a "feeder coach" and you have to change your coach at their own coach station but they transfer the luggage for you and there are usaully free refeshments whilst u wait.
The evening entertainment though is mainly for the oldies, though not always, but u can always go out and do your own thing.
David Urquart similar coach holidays usually have a younger crowd but not as young as you guys, but they dont make you change coaches.
Also if the drop off point is not very convenient for you & u let the driver know where u want to be dropped off and offer him a fiver, he can usually make an unscheduled stop.
