We were last there in June, so I can't speak specifically about August, however, if you don't think your little one would take waiting in line for a long time I'd go ahead and get the package. I've never used the package but we haven't had a 3yo with us either. If there are two showings, the last showing isn't nearly as crowded as the first, but I don't know how your little one does with being out that late.
We will probably have to do the dinner package next trip however as my granddaughter probably won't cooperate with long line waits at 16mos.
