I always went with the idea, "I'm on vacation and I'm not going to wash clothing." But this past week, while we were traveling, my DS was sick and soiled some of his clothing. In this case, I HAD to wash his clothing and I figured, while I was at it, I might as well wash some of the rest of our clothing.
Turned out the washing machine was on the way to the pool and we could play around in the pool while we waited for it to wash and dry. It worked perfectly. We had clean clothing for the rest of our trip and, once I got home, it worked out that I didn't have like a billion things to wash. It also made it so I wouldn't have to bring as much, something that I totally am a big fan of.
Anyway, we're heading out for an extended trip in December and I'm thinking then, we will just wash our clothing.
