That soon in the day, they may not even be offering fastpasses yet! EE is a popular ride, but not THAT popular. If I recall from the last visit, we nabbed fastpasses at about 9am (the park opened early at 8am) that had a return time about 30 minutes later. Later in the morning, probably around 10am, we got FPs with an 11am-ish return time.
My advice is to hit EE first, see if there are FPs available. If so, get some and ride in the standby line (it'll still be quite short early in the morning). Keep riding as many times as you can in the standby line, until your FPs are up. Then use the FP to ride once more, then move onto the rest of AK. You'll probably ride it at least 3 times this way, in very short order.
