First of all, jrm27, welcome to RFF!
You have a lot of good and varied advice here. I can speak to the compact, fixed-lens rangefinder cameras, such as the Canon QL 17 GIII, which I have. I have used such cameras, with total satisfaction, for travel photography, because they were so compact, light in weight, unobtrusive, and easy to use. I always got sharp, well exposed slides with mine.
The shutter-priority automation was convenient, while providing manual-equivalent exposure. You achieve AEL (auto-exposure lock) by pressing the shutter button half-way down. (Aperture-priority or shutter-priority automation serves me well, as long as I have AEL. Otherwise, I find said automation useless.) The meter doesn't work in manual mode.
These cameras required a mercury battery, but an MR-9 adapter plus a 386 (flatter than more standard 357) silver-oxide cell should fit and enable the camera to work as designed.
You can also enter the guide number of any manual flash, and the camera will provide auto-flash.
The Minolta Hi-Matic cameras are also very well regarded, and they have the same features as the Canon.
