Lines were insane Sunday night.  Minimum waits for houses started at 60 minutes, went up to 90 for TWD, rides were at an hour, too (other than DM:MM, which seemed to top out at 30).  Keep in mind, this is still only the first weekend in October.  If Universal doesn't have a contingency plan in their back pocket, I can only imagine Hell Week will see 2.5 - 3 hour lines.  Not sure how the General Public will feel about waiting an hour to get in--happened Friday night with the new stricter security--then only doing two or three houses.
