I am fully aware of Barrhead Travel and I know that they are HUGE in Scotland and the North East but we don't have a comparible company like Barrhead Travel in our region especially one that has a tour operation of their own. The only company locally that was capable of doing that was Bath Travel as in Palmair but they stopped serving SOU over 10 years ago and was more of a BOH operation.
As I posted before Adfly sums it up well.
