We need to skip seeing one park on its early morning hour day. Here's our group: grandparents (60's), DH, me, DS(9), DD(6), and DS(1). I know DH and DS want to do Test Track. DS might want to do Tower of Terror, Rock 'N Roller Coaster, Dinosaur, and Primeval Whirl, but probably won't decide until we get there. Which early morning hour do you recommend we skip and why? (Skipping MK is NOT an option!)
