Trying to figure out what to send ahead since we'll be washing sippy cups and other baby items a bunch. As I was doing dishes this morning it occurred to me.
I've read a tip on here that what some people do is cut sponges up into smaller pieces, put dish soap on each piece and let them dry up, and then when they wet the sponge again while at the hotel, it's already got the soap in it. Seems pretty easy if you're short on space!
I've done this before and put them in a tupperware container. Works great!
