All my lists are arranged either by Destination or Category.
Use the menus on the left to drill down.
I list firstly, British tour operators or specialist travel agents who feature that Destination or offer that Category of holiday/travel/excursion/attraction/service.
For many destinations and holiday types I also list a few local travel providers and accommodation.
There are holes (lot's of em!). Not every destination is covered nor every activity/service.
