It is best to buy a BONO which means a PASS.

https://granadamap.com/car_parks.htmWe get loads of questions such as: I am staying at XXXX hotel. Where can I park?
Many hotels have special deals with car parks and specific arrival instructions so it is best to ask the hotel directly. I would personally cancel a hot and book another if they cannot give you any help with where to park.
