Lydia,
So glad you find the Moms Panel useful!! Thanks for letting us know.
I also don't see Finding Nemo on the Disney Entertainment Calendar for those dates, but that is most likely just an oversight. My understanding is that the show will be running several times a day (as usual) during your visit. Keep checking back periodically to see if Disney has updated the calendar.
You can also visit Steve Soares' unofficial site (click
HERE and click on the "Animal Kingdom" link at the top of the page) which does a great job of listing the times for many different shows and events - it is impressively comprehensive. Since Disney doesn't publish times guides very far in advance, Steve can only update his site for one week in advance - which he does each Saturday night. So, definitely a good site for you to check out on Sunday, May 2, before you head to WDW.
Also please be sure to also pick up the "Times Guide" when you enter the park, as that will have the latest information, and show times can change at the last minute.
Hope that helps!
If you have any follow-up questions, please feel free to submit them using the "ask Bret a question" link
on this page. (Note: you can submit questions to other panelists in the same way, via each panelist's "Meet the Moms" personal bio page)
