Hi Anetra,
The
Move It! Shake It! Celebrate It! Street Party is indeed still going strong at the Magic Kingdom. Disney doesn't list the times for it on their online calendar. However, there is an unofficial website that usually posts entertainment schedules for the parks about a week in advance -
www.wdwent.com. You can also search Steve Soares on the internet and his site should come up.
This site typically updates the schedules on Saturdays so be sure to check the website the Saturday before your trip. Again - its unofficial but I've found the information to be pretty accurate.
When you arrive at the Magic Kingdom, be sure to pick up a
Times Guide to confirm the times on the day of your visit as schedules are always subject to change without notice.
Times Guides are available at the entrance of the park, Guest Relations & most merchandise locations.
Wishing you many magical memories :-) Allison
