Update: I should have checked the available entry times for the Nasrid Palaces before my initial post. Tickets for the Alhambra are timed, with the time indicating when you may enter the Nasrid Palaces (the highlight of the complex). You may enter the grounds of the Alhambra and see other buildings before the time shown on the ticket.
The Dobla de Oro tickets now available for March 10-12 are for entry times beginning at 5 or 5:30 PM. I think that would be workable if you saw everything else before going to the Nasrid Palaces, but that would make me a bit uncomfortable. If you feel the same way, there is another, albeit somewhat more expensive option--the Granada Card. The Granada Card is a sightseeing and transit card sold by the Granada Tourist Office. It currently has earlier Nasrid Palace entry times available for your dates, but probably just a few of them. I think the Granada Card includes all the sites covered by the Dobla de Oro ticket (possibly a few others), plus some transportation benefits. You'd need the 48-hour ticket to have daytime access to the Nasrid Palaces. That costs 55 euros.
