I have a quite specific question about visiting the Alhambra, and I would appreciate any help you could give. I am trying to sort out the whole issue of what time to book and the order in which to visit the various sections. Do you really need to be at the entrance to the Nasrid Palace exactly at the start of your alloted half-hour, or is it possible to still be let in at any point between say 2.00 and 2.30 if your booking is for 2.00? I would like to let the bulk of the people through first in the hope of it being slightly less crowded when we go through, but I have read that you only have a 5-10 minute window to get let in. Many thanks for your help.
