Book the Alhambra before you book your flights
Nasrid Palace slots sell out two to three months ahead in April, May, and September. Check availability at tickets.alhambra-patronato.es before committing to travel dates — there is no point arriving without a slot. At midnight each night, cancellations are re-released; if your dates are sold out, set an alarm. Book your Sacromonte flamenco show the same session: cave venues seat 20–40 people and fill at similar speed in high season.
