Spent a year there as a USAF officer ground controller. Took lot of pics with my Nikormat. Have great memories living in a hootch. It was either join the Airforce or get drafted after college, and in those days they were drafting marines as well-life expectancy was 30 days--no thanks. All us guys were just trying to stay alive and get back home. And today, I put my digital camera into a nice camera bag that I bought about 5 years ago at the local camera store--and inside was a tag: Made in Vietnam--so all is good lol. And the island, Hon Tre off Nha Trang mainland, I spent most of my time on is now one of the best resorts in Vietnam. Google it and look at the images--cracks me up.
Make sure your sons and daughters take a good pocketable camera over to North Korea--it will be their next stop, and possibly they can get a nice shot of a mushroom cloud. Sorry to be cynical, but the world continues to be both a dangerous and beautiful place.
I chose the RX100 for a trip to Germany rather than taking my Canon T3i along. I also took a Panasonic 3D1 along for 3D. I had each in a small case attached to my pants belt. I used the 3D1 for most snapshots and the RX100 for scenics. And wow, the RX100 truly did the job, and the panoramic mode is jawdropping. I've got some outstanding castle/river shots. I created a 15'x11.5' photo book through My Publisher using their hi-res glossy lay-flat paper, and far exceeded my expectations. The panoramas fit across two pages thus some being 11.5"x30" and everyone that sees them are amazed at the image quality. The 3D1 does a reasonable job for 2D images as well. The two cameras were a great combination, and I'm now selling my T3i on ebay. If I do miss something about the DSLR, it would be the need for a greater zoom, but as I found out, the resolution is so good on the RX100, you can simulate a 200+ zoom with little loss. I feel the need, the need for more travel.
