No, it is not if you are a US visitor. You would have to get an annual pass for more than 10 days.
Most either don't go to the parks every day on a long trip, or purchase the waterparks option which gives you (on a 10 day ticket ) 10 visits to the waterparks and Disneyquest.
Just so you know, a 10-day ticket doesn't expire until day 14. So, if are there for 12 days, but only plan 10 days in the park, the 10-day ticket will work.
