Amazing place, but be weary of booking via this option if you’re restricted on times to visit Nasrid palaces.
We booked both, but received a message before we arrived saying our entry to Nasrid Palaces was only for 19:00.
The rest of the Alhambra is a very enjoyable 3-4 hours, but because we couldn’t wait to enter Nasrid Palaces until our allotted entry of 19:00 we wasted money booking this also.
It does say in small print this could change, so if you need a specific time I’d look elsewhere.
