I know many here don't tend to do guided tours, but I have found this works for us in the 'big' sites (hubby doesn't do much research other than watch the RS's videos, and listens to guides but not me reading from the guidebook :-)). I have booked a RS's recommended guide to take us through the Alhambra when we are there in October, and tickets just went on sale. Since this is a private tour, we can do the sections in any order and looking for thoughts/experiences. I'm considering booking the Nasrid Palace entry for 10:30. The time with the guide is 2.5-3 hours. Had thought about meeting at the Alhambra in the morning when it opens, tour the other areas and end with the Nasrid Palace, and be able to stay there after when the time with the guide is done. Or might it be better to start with the Nasrid Palace, do the other sections (maybe end with Generalife), and then be able to stick around there when time is done? (Or other ideas entirely that I've not considered.) My understanding is each section you can only enter once the day of your ticket, and the Nasrid Palace only at the allotted time.
We enjoy learning about history and pretty scenery (i.e. gardens in this case). I know I'm overthinking this, although getting very excited for our trip! We are in Granada for 3 nights.
