I'm going to Hawaii in October and I plan on bringing all my current gear. It all fits in my Think Tank Retrospective 10.
However, I won't be carrying all my lenses at the same time. If I'm out at the beach I plan on bringing my zooms. If I go out to a luau I'll bring my 24-70mm & my primes (I think the 70-200mm f4 IS might be too slow for late night shooting at a luau where they got the guys dancing and throwing flames and stuff). Walking around during the day I might bring my 24-70 and 50mm.

Now my next decision is if I should bring my tripod? Manfrotto 190XPROB with a 488RC2. Decisions... decisions...
