I haven't posted much here lately. I've been engaged in some other pursuits and work that have taken up most of my time. As a result, I'm taking a week off and going on a "do over" trip the end of this month.

It's a "do over" because I did exactly the same trip last year, but somehow I lost the souvenir I bought for my granddaughter, an obsidian cartouche with her name in silver in the Mayan alphabet.

Last year, I packed one suitcase, including my tuxedo, and my Airport Essentials gear bag. I took everything: D7100 body, 10-24mm, 18-55m, 35mm, 18-140mm, 55-300mm, charger, SB-700 flash, and assorted lens cleaners, cables, caps, etc. In addition, I took my laptop and tablet and their chargers.

Part of me thinks the reason I had some issues with my camera requiring Nikon repair (twice!) is that I over-packed and that gravity and the forces applied by carrying all that gear caused some banging that threw the camera out, requiring repair. I hope to avoid a repeat of that.

So, my thinking is that I can cut back on lenses (maybe just stay with the 10-24, 18-140 and 55-300) and perhaps leave behind the wireless mobile adapter and other gadgets. My chief aim is to photograph the Mayan ruins at Tulum, Mexico (it was raining last year, so while I got some decent shots, I'd like another "do over" there, too).

Any suggestions from the veteran photo-travelers here?

I would have to agree with Antonio. I've been many places around the world from cities to wilderness and unless you are specifically going after wildlife photos, I think anything longer than the 18-140 will see little if any use. While a wider option would be nice, it too could be unnecessary, especially if you can take a few images and stitch them for a pano. I tend to fall on the side of leaving the tripod at home. You're on vacation, after all, not an assignment, so be kind to other travelers and your back and shoulders and keep your kit to a minimum.
