I am trying to schedule around my DH's convention mtgs...
What time is The Finding Nemo show shown?

The show times vary depending on the expected crowds - but if you look at Steve Soares' website (here (http://pages.prodigy.net/stevesoares/)) you can see the current schedule to get an idea.

FINDING NEMO -- THE MUSICAL
The undersea world that charmed audiences around the world in “Finding Nemo” comes to life in an all-new musical stage show in the newly enclosed Theater in the Wild.
Please arrive 45 minutes prior to performance. No admittance after show starts.
10:00 & 11:30am, 1:45, 3:15 & 4:45pm

so this is my answer...it took some digging but I found it...thanks.

Just know that if you got that from Steve's website- it's the CURRENT schedule, and they could easily change it and cut out the number of shows if you're going at a slower time of year - or add more shows and move the times around.

In this link is says that Steve(or the person that used to do it) isn't doing this anymore...they are looking for another cast member to take over....
(btw...going 3/27-4/3!...busy)

According to this page on Steve's site (http://pages.prodigy.net/stevesoares/) he's still doing it and the schedules posted are current. Where specifically did you read that he wasn't doing it any more?

Interesting - I wonder why he doesn't have that on HIS website anywhere...

ETA: I just noticed that post was from July - he's probably found replacements, and hence the request isn't on his site.
