I would not bring all that gear on your list... it will end up weighing you down and impacting your relaxation and enjoyment. IF you bring the 5D3, I'd probably just bring a general purpose lens like the 24-105, and maybe a 75-300. The 5D3 has such amazing high ISO and resolution that you should be able to get what you want, even in low light. I don't have a 75-300 (yet), so I'd probably be inclined to bring my 135L and TC1.4, which is a nice light package to get the long shots when needed, and is a great portrait lens too. So for me, I'd through in the 24-105, 135L, TC1.4, and maybe my Sigma Fisheye because that's always good for some fun shots.
I took the 5D II, 24-105, 16-35, 70-200, Tripod, Pano head, Nodal Slide, cleaning pads/cleaner (DO NOT FORGET THAT!), 2 Lee Foundation Kits and plenty of filters. Also took the G12 and Olympus TG-1iHS underwater camera.
What would have impacted my relaxation and enjoyment would have been NOT bringing all the equipment and not being able to do landscapes.
