I'll add another "what I did take" story...on a 14 day Hawaiian cruise.
Fuji X-E1 + Fuji 18-55, Fuji 60, CV 12/5.6
Like Jeff, the only camera that came out of the bag was the RX100. Even though I've been using the RX100 since it was released, I was still amazed by how versatile and capable the camera was for the situations I encountered, and how good the resulting images are.
I think one of the main points to understand about why the RX100 worked so well for me was how the tours I went on were structured. I went on several helicopter tours where you can't take a bag with you onto the aircraft. You're strapped in with a 4-point harness and wearing a flotation device (these flights spend a significant amount of time over open water), so even if I'd have had extra lenses for the X-E1 in the pockets of my cargo shorts, it would have been impractical to swap while in flight. It would also have been difficult to manage multiple cameras for the same reasons. The 28-100 range of the RX100 was just about perfect.
In addition, being in completely foreign environs with little to no time to work, having a camera that's for the most part competent on it's own worked great. I only had to intervene a few times in extreme contrast situations, and I noticed a slight tendency toward overexposure. I lost some highlights, but was surprised how some limited recovery was possible with the OOC jpg files. Since my goal was producing vacation snapshots and not pristine commercial work, I was very happy with the results. Overall, image quality was by-and-large fine. It's a small-sensor compact, after all, so I wasn't expecting the same quality I've gotten from full-frame DSLRs or the X-Trans Fujis. But it's no slouch...far and away the best quality compact I've ever shot.
Handling of the camera was fine, although I have added the Franiec grip and strategically-placed bits of gaffer tape. Slippery is not a word that comes to mind when you pick my camera up. The shutter button is a little indistinct for my taste, and on several occasions took photos when I intended to half-press. I alternated between the Sony-supplied wrist strap, and a neck strap from a Ricoh GRD I had a few years back. I ended up turning on the electronic level as I was getting alot of unlevel shots without it...probably mostly due to the quick grab nature of alot of the shots, but the level helped.
On several occasions, I handed the camera to complete strangers who were obviously not camera experts to get shots of my family and myself. On purpose, I didn't coach them at all when I gave them the camera. They were able to zoom, compose and shoot rather intuitively. I think that speaks to a successful interface, or at least to the ubiquity of enough common interface elements in modern digital cameras to get the job done.
Overall, the RX100 did a great job. I could have left the Fuji cams at home and not missed them at all...which is not something that I could have been convinced of prior to this trip.
