I vote for somthing in the 35 to 40mm range ad the 90-135 range. I am very partiial to 40mm and 90mm amd most of my fixed lens cameras are 40mm as well as having a 40mm for my slr and interchangeable rangefinder. I prefer to 90-105 range for a somewhat longer lens especially for portraits and strret shooting. 135 id too narrow for my liking when walking the streets. My has a 105 anf interchangeable rangefinder a 90. Now, admittedly, I have an excellent doubtler for the slr so I can use the 40 and get almost to the 90 or 210 with the 105. The key with these is to get the best you can, firgt thinking they can be had for cheap.
The way I shoot, 50, 28, and 21. You could chop that down to 50 and 28 easily and I'd still be happy. I'd also be mostly happy with just 28. Or even just 21 if my 21 was faster than it as (it's only f/4.5). The couple times I've brought along a 90 (in a 28/50/90 set)... I used it sparingly but got to the point where I stopped bringing it.
Others might like just a 50, but I'm much more comfortable with 28. So assuming you are like me, I might consider going with just the 28 and 50. If the 28 isn't your main squeeze, then maybe the 20 and the 50. And if you want three lenses but don't care for wide as much, the 28/50/105 (or 20/50/105). It really depends on your preferences, which I don't know. I would recommend keeping it to two lenses, three tops if they are small.
Thanks everybody for their experiences. I have some time before we go and this might morph but I think I'll go 20 - 28 - 50 - 105. I might drop the 20 unless the wife says she's expecting interiors, then I'm stuck with it. But it's small so no big deal.
Although the 28 is my "main squeeze" I've been shooting a very old 35 f/2.8 and really liking it, so maybe I just adapt my eye to whatever glass is on the box. This is very important because it gives credence to the 'one lens, one camera' thing mentioned here. Something Zen about that, but I don't go on big trips much anymore so I'll do a CYA on this one.

When I want to go light and walk a lot it is 20/50/100 for me. If I want really light 20/50 or just the 50. Taking more is just a constant battle of what to use and 20/50/100 is sufficiently different to know what you'll use and why.
I used to go 28/50/100 but I kind of started to like the 20, if you want wide then go WIDE!
