Are you doing Animal Kingdom or any of the other animal parks? If so I'd take the longer zoom one, as well.
Me I'd just take the 24-105 - you will know about it lugging around the 70-200 all day in the heat for the one shot you will use it for, but maybe thats just me - 24-105 perfect range , can't think of many long zoom shots I'd need at Disney aside from a day at AK then I would take the 200
Depends what you want to photograph really, simon always get frustrated with our 70-300 not being enough for the animals
Just as I was thinking, thanks the 200 isn't long enough really and I can also take the smaller camera bag, thanks
Well....I finally ordered it, out of stock at the moment but will get it in plenty of time to practice!
