I'm a D800E owner too, I feel your pain OP. I want to bring my dslr and all my lenses with me everywhere, but it can become a PITA. I just recently purchased a Fuji X100s - only 3 days use so far and I am already in love! This is the only camera I will take to Turkey at the end of the month.
Get a case for it! use the provided neck-strap ... sheesh ... there are many options available to keep it unobtrusive.
All I can say is the X100s is the nicest, most comfortable, best behaving, best quality camera I have used, in this price range, for a long time. It beats the pants off the Sony RX100 [which I just sold on to buy the Fuji] - Forget size. the Rx100 was so small I was always afraid it would slip out of my hand, and that was with a rubber grip I added to it. I also found the controls less than brilliant on the fly. Way too fiddly.
The X100s gives you better quality images, better high ISO performance, better 'bokeh' and better all-round controls. Takes a day or two to nail it, then it's down, and becomes very intuitive. It continues to impress me with use.
So it's a fixed WA lens - I have thought on this point - and then i reckoned ... I don't actually use zoom or longer lenses when I'm abroad - i tend to take in the scene - and the quality is that good I wouldn't mind having to crop whatsoever.
I am not paid by fuji for this post btw
I just really do love this camera. Get one, now!
If you don't love it after a few days and a good getting-to-know session, well, you'll sell it at no loss easily. People are crying out for them.
Not a great example, but I have just been putting it through it's paces, this pic of our new kitty was shot at f/2, ISO 3200 -

I shot a party with it last night, never brought the D800 along - and it was great, people were ogling over it all night. My D800E, with the best lenses I could stick on, never pulled that kind of reaction.
