While I like kickstands, I do not use them do to the weight. If I used one again, I would only use a rear triangle kickstand. I have tried most, and they all have pluses and minus.
The regular by the bottom bracket pro is easy, familiar, and cheap. Con is it can mar the frame unless a dedicated kickstand plate is built-in. Can't back-pedal if the stand is down.
A regular rear triangle stand's (mounts on the seat stay AND the chainstay) pro are it is very durable, can back pedal, but the front wheel can be squirrely at times. A bit heavier and more costly though still relatively cheap.
A double stand by the bottom bracket's pros are the bike is stable but can't back pedal and are heavy and more expensive.
A Clik Stand (or similar versions) is lightweight but not near as steady and expensive.
I have not tried the front rack version nor the rear stand that mounts solely on the chainstay (that one scares me a little). I just lay my bike gently down if a wall, bench, or other bike is not available. Since it sounds like you will be traveling with your wife, you should know that you can lean the bikes against each other (but front to back reversed) quite easily and I do it very often when touring with someone. This is a bit harder if one bike is much smaller/bigger than the other. In my 40+ years of touring I very rarely absolutely needed a kickstand though they are nice to have if you are willing to put up with the extra weight.
If I were doing a regularly loaded touring bike, I would use something like a Greenfield Rearmount Kickstand. If the bike was a very heavy loaded touring bike or a tandem, (50+ pounds of gear w/o consumables), I would probably use a double bottom bracket stand, ideally with a dedicated kickstand plate.
