//...once all aboard all the staff of the hotel piled out lining the pavement, waving to them all as the coaches pulled away. What a load of tosh.//
It may seem a load of tosh, Sandra, but that large party (and others like it) could be the difference between the hotel staying in business or going to the wall (which, if it had, would mean it would not have been available for your overnighter). The staff may have been wise to that and appreciated the oldies' visit, hoping they would come again.
On a wider note, coach trips suit a lot of older folk, especially those who live alone and who may no longer drive (or perhaps never did). The transport is sorted and they need not worry about booking accommodation, etc. As well as that, many like the company that a coach trip provides. Certainly not for me, but it takes all sorts.
