Can't answer the specific question about pre booked times at the Nazaries Palace but I hope my comments will be helpful. If you are anywhere within a day trip of Grandada, Alhambra should be on your "must visit" list - with or without Nazaries Palace. Go with an English speaking guide, or buy a good quality guide book, and arrange your holiday dates to make sure you get there - yes, it's that special.
Confession time. I don't know which of the WOW!!!! moments on our visit were in the Nazaries Palace. I only know that a lot of them were not. Conclusion - this is an unmissable place even if you never see the Palace. In the current UK climate when the gutter press are trying to portray Islam as the source of all evil, it's not possible to spend a day at Alhambra without appreciating that this is a culture of awe inspiring beauty.

Huh? "Unquestioning support to a monarchy"??? Which monarchy would that be?

Do you know anything -- anything at all -- about the Alhambra?

I suspect not...

I just made my reservation today 9/4/05. It was a very user-unfriendly website that left me rather confused.
I preferred the morning, but I ended getting a slot at 1:30PM in the afternoon as all the morning slots were taken.
Is this considered a morning ticket? Meaning I am allowed to enter the premises at 8:30AM, visit the Nazari Palace at 1:30pm and stay as long as like in the Palace and the rest of the premises until 8pm? Or does it mean I have only 1/2 hour to do everything because the "morning" shift ends at 2PM.

Unless you get authoritative information indicating that you can stay beyond 2:00, plan to arrive in the morning and spend four or five hours seeing all of the the Alhambra except the palace, so that after your 1:30 palace visit, you will have seen the entire place.

Mosquem, I too ended up making my reservation through the website for a morning ticket with a Palace visit at 12.00, and am still not clear whether I have to leave at 2pm. When are you going? My visit is booked for Sunday 11th September. If you can wait that long, I can find out and let you know.

Conclusion - they definitely allow you to stay as long as you want once you are in there. I had a morning ticket valid for entry until 2pm, and our only problem was that the eating places are limited inside and we had to eat lunch (outside) in a hurry in order to get back in before 2pm. Once we were back in though we could wander at will. Hope that helps.
