I found a little shoe organizer for shoes, not one of the pocket ones for toiletries, but one that looks like little cubes stacked on top of each other for actually controlling the shoe population in the room.
They were $2 and hold 6 pairs of adult shoes. I figure I could probably put three pairs of DD's shoes in one, I usually have one pair of tennis shoes and several pairs of flip flops and DH has two pairs of shoes with him. That it would be good enough to keep us from tripping over the shoes.
When we go down, I have a large rolling duffle bag that I use to put in things like the shoe organizers, etc. By the end of the trip the amount of stuff in that bag has decreased enough that I have extra space but we have a smaller folding duffle that we bring down empty so that we had an extra bag just in case we need it, and if we don't it folds flat and just goes back into the duffle.
I also bring a small IKEA step ($3) for DD so she can reach the sink to brush her teeth, it's just a little plastic rectangle and when I turn it over I just put things in it so it doesn't waste too much space. It just beats having to here her ask to be picked up to wash her hands, brush teeth etc.
I'm another one folks who has a binder with all my information in it. It is affectionately known in our house as "The Great Big Book of Everything." Thank you Stanley! I also have little 3 x 5 cards with our daily information on it, ADR's etc., that I carry in my bag.
Thanks to this board I have a great Baggalini bag that I use in the parks. I love it.
We also do a lot of the above mention things like outfits in ziplocks. I also have little bags that live in our vacation box (it's just a plastic tub that lives under my bed) like a laundry kit, dishwashing kit, travel games kit, pressed penny books, special sharpies, a light spinner we picked on a previous trip, clip on fans, mister fan, just to have everything we only use on vacation at hand. A few weeks before we leave I check to see if anything needs replacing or replenishing. This is all the stuff that goes in that duffle.
I want to thank some of the PPs for new ideas, like the pop up laundry bags, I went and grabbed a couple at the dollar store so we didn't have a messy room! Great ideas! Keep 'em coming!
