I haven't been to EMH in OCT, but in February, another slower period. It's still crazy for the evening EMH, as not many attractions are open at those parks. Last Feb. (we are going again in 3 weeks), the only attractions open in AK were in the DIno area. Dino was a 45 - 70 minute wait, so we got a FP, walked around, and then there wasn't much else to do until our FP time.
MGM was better, but still difficult on the popular (RNRR and TOT), but some of the "good" rides had small wait times.
I'll let you know in 3 weeks if anything has changed
