BBC had an article about a couple who have booked 2 holidays at the same time. One in Devon and one in the canary islands, so if the Spanish one can not go ahead then they will go to the Devon one. They are taking advantage of the Devon one wanting to give holidaymakers peace of mind by offering free cancellations. They have no intention of going to the Devon one. Despicable behaviour IMO. Their faces and names are on the report, if I were the hotel and I saw that BBC report I would be contacting them and telling them to Foc off.
Apparently many people are doing the same thing, all these fully booked hotels - come the time they are going to find themselves fully empty.
