In my experience this season AVP is the first Finnegans house. Walking Dead opens at 6:30 BUT the line is allowed to form before that...how much before that, Im not sure, but the second time I went this season I was in line for TWD by 6:15 and waited a little over an hour for it. On one hand, you might want to get to Walking Dead first so youre one of the first in line at 6:30...but at the same time, an hour wait isnt bad and waiting only 10-15 minutes for AVP is pretty solid. It really depends on your touring plan for the rest of the night.
