Originally posted by wibbly you don't need any reach at all for these places. you'll either want to get the big picture (ie some of the massive installations there), or take photos of family.
I can think of one exception: Animal Kingdom. Riding the Kilimanjaro Safaris, it wasn't long before I found myself wishing I had a telephoto zoom of any kind.
I'll also mention that the Rokinon (Samyang) 35/1.4 really came in handy for indoor shots of my own preschooler, like when she met Minnie/Daisy/Donald/Goofy in the big tent in Toontown Fair or Mickey in the Main St. theatre. Or even for
this outdoor portrait, which is now hanging on our wall.
Of course, that was with only one child to worry about. I don't know if having more than one makes it that much more difficult to change lenses.
