Turtle Talk is a MUST see, especially with kids that age!
I was at WDW week before last and this is how we did Turtle Talk and it worked like a charm!
The first Turtle Talk show was at 10am, so we got to Epcot at 9am, we headed straight to Soarin' - the wait time said 30 mins, but the CM told me it was really only 10 minutes....so we rode Soarin' - (I don't even think the wait was 10 minutes...) and then on the way out we grabbed a Fast Pass for Soarin for later and then we went to the Living Seas. If the Soarin' line really is long though, just grab an FP for it and go over to Living Seas. That is what I was going to do, but with such a short wait at Soarin', we decided to ride right then. Soarin' and Turtle Talk are pretty close together, that's why I went to Soarin' first instead of Test Track. Anyway, we got to Living Seas about 9:40am and got right in line for Turtle Talk, there was about 30-40 people ahead of us already in line, but we got into the 1st show.
We went back to Living Seas around 12:30 and the line was OUTRAGEOUS!
All the way back to the escalators! -- I think if you don't catch the first show
or maybe the 2nd Turtle Talk you are in for quite a wait later!
After Turtle Talk/Living Seas we went back and did Soarin' again and then went to Test Track and got an FP for that.
It worked out really well this way. Course it wasn't at all crowded the day we went...but still I definitely recommend hitting Turtle Talk first thing, especially since it is not an FP attraction.
A friend of mine was at WDW last week and they didn't even see Turtle Talk, she said they tried about 11:30am, but the line was just too long.
