The UK law is by precedent, which is decided by a judge ! So if other hotels have been granted planning permission ( bear in mind it is the planning committee that grants permission not the council officers ) then you are on to a winner. The council will have to put an enforcement order on you to stop you doing it. This is very expensive for the council to do, it also means you have to go to appeal again expensive. By that stage the laws of precedent will be used. Hence if other places have planning permission then hey presto !
I should know I had the laws of precedent used by my local council, they used AlFyed landing on the roof of Harrods as curtlidge v my garden on Dartmoor !!!!! The planning committee laughed the planning officers out of the room for using this example
