Thank you for all those providing information on this thread it has been so useful.
We attended on Friday (02/21). It was absolutely freezing, even for a family from the UK. We arrived at the main gate at 6:30 and walked straight in, so I’m not sure what time they started letting people in. We’d booked Fastpasses for Buzz, Peter Pan and Jungle cruise and did those 3 along with People Mover, Laugh Floor, Teacups and Small World as well as watching the fireworks before the party started at 9.
At 9 o’clock the headliners were still showing 50 mins wait, so we looped round doing Little Mermaid, Dumbo, Barnstormer x3 and Winnie the Pooh. As we exited, SDMT was showing 20 mins (just after 9:45), so we jumped in the queue and it was walk on. We exited to do the ride again, and waited around 10 minutes.
After SDMT, we headed over to Space Mountain where the posted time was 5 mins, but this was again a walk on. We looped round to re-ride and waited a little longer this time (maybe 10 minutes).
We then did Buzz again two more times, leaving ourselves an hour to do the other side of the park in which time we did Jungle Cruise, Pirates and BTMR x2 (all walk on). All in time to watch the parade at 11:45.
We absolutely loved it despite the weather and felt the park was quiet and queues almost non existent. We also stopped for snacks twice.
I hope this helps...
