Scenarios are infinite without any constraints, so I'll just go with everything the same as right now, except money is no constraint. Also assume that WDW is still a vacation (meaning I don't want to bring any assistants or carry too much gear).

Nikkor 14-24 2.8
Nikkor 24-70 2.8
Nikkor 70-200 2.8

I would carry 5 lenses at a time, with the top three always in the bag. What can I say, I'm easy to please. I don't think I'd really use any more exotic glass at WDW.
