Ok, I've posted this before but I can't remember if it was here or not. So, just in case! My DMIL gave us sponges that were soaked with dishsoap that had dried. I was reading about the much missed Palmolive towels and I thought I would suggest this instead. She even cut them into Mickey heads! That way, we didn't have to take down any liquid soap and we could wash up plates, spoons, and sippy cups for DS.
I've also found giant (I mean giant!) ziplock bags recently at our Dollar Tree. They come in L, XL, and XXL. I'm sure someone already mentioned those too, but we use them for everything. Packing, toys, swim stuff. I used one the other day to keep a cake from drying out that was on a tall cakeplate. Way faster than foil and the whole cake was covered.
DH and I take a handful of clothesline type clamps to hang a towel over the vent. They were from Ace and came in a giant tube for $3.99 for around 25, all sorts of sizes. It seems like the air would blow right on to the bed and we wake up with sore throats. This way, it still keeps the room cool but goes straight down instead. They also helped keep a stroller cover down in the back.
We use hooks with suction cups to hang the suits in the shower so they don't leave water all over the bathroom floor.
We bought a waterproof carrier that keeps our keys, cash, and cell phone totally dry. That way, we can leave the bag behind without risking the important stuff. DH just puts it in the zippered pocket of his suit.
I did read way back in the beginning of the thread someone that said they used the icebucket for a bathroom caddy.
I know the last ice bucket we used had dirt and dust in it, so I'll pack my fold down shower bag instead. And, at the risk of sharing too much, I used one for a morning sickness receptacle instead of not making it to the bathroom. I just threw it away and said someone took it while I was getting ice. I don't think they believed the story, but that's ok.
