We went on a Thursday in October and here was our experience with posted wait times on the major rides.
Rise of the resistance: They set the time at 60 pretty much the whole day. We rode it twice and the first wait was 40 and the 2nd wait was only 20 (60 min wait posted). Here is my opinion. Go around 1:30-2 or around 630-7. After major meal times worked for us. Also, if Disney lowers the time from 60 to anything less then be prepared for a rush.
Slinky dog: We rode this twice (once with LL). We got in line at 8:40 PM with a posted wait of 90 minutes. We waited 30 min and still made Fantasmic. In my opinion Disney won't reduce the time on major rides late at night to deter those of us who want to hang out after park close. From 8-9 PM we walked on Aliens, Toy story mania, and rode Slinky.
We were able to ride the following rides twice at HS: Rise, Smugglers Run, Slinky Dog, star Tours, Toy story mania (3 times), alien saucers. In addition we were still able to get on all the other rides once. We are a group of 6 with 4 kids under 12. Just do your research with Robs great content to maximize your day!
Good luck!
Thanks for this thread - we have also been noticing some pretty inflated wait times lately. It is not ALWAYS inflated, so it makes it hard to say you can count on it, but there are certain rides that seem to be regularly overestimated. Toy Story Mania has been a big one recently.
