Pack the kids clothes in outfits in gallon ziploc bags and squish all the air out
Have a great trip!
Did not read all of the posts but this does work. You can do this for the adults clothes too. I think it if Hefty that makes a 2.5 gallon size bag. Makes getting ready in the morning easier (DH didn't have an excuse not to help), just mark the bags with the day. We also put our clothes at the end the day back in the bags and squished the air out, made packing for the return trip easier too.
If you plan on doing laundry while there, Purex makes 3 in 1 sheets, pop a few of them in a plastic baggie and you are all set for laundry supplies.
When I pack, I put all of the clothing on our bed (a stack for each person), the suitcases next to the bed and then start packing. I do not pack a suitcase for a specific person, I divide everyones things up and split it between all of the cases (if a checked bag is ever misplaced, no one is at a total loss there is always clothing and other personal items that can be used in another case). The must have things go in first (trial size - shampoo, deo, meds etc ). Then I do shoes, we wear our bulkiest pair of shoes which are normally sneakers, so that leaves us with either sandals or
crocs or both ( I normally end up with shoes at the sides or ends of the cases) I then do the clothing, 1 set per person per case. Once that is done, I then just take one set per person and just randomly throw it into one of the suitcases. If there is any additional space I will then put in another set per person just randomly into one of the cases. Once I am out of room, that is it, rest stays home and we do laundry if needed.
If we need to take coats we wear/carry them onto the plane. If it gets chilly they can be used to cover up and a few times we have bunched them together to make a pillow for one of the kids.
We normally do 2 backpacks. DH carries one backpack that goes under the seat that has stuff just for the kids to do on the plane and individual packed snacks and also 2 cups with lids and straws (open cups and kids do not work) My backpack has all the camera/video stuff, all the other important cannot lose stuff, prescription medication, bathing suits and toothbrushes (never figured out how to pack those two items if we ever lost a case) I carry that one because I am used to carrying something and definitely do not want DH to get up and let it sit because it is not a normal thing for him to grab and go. If it is a long plane ride, we will do a 3rd backpack with an extra set of clothes for everyone just incase of sometype of accident.
Wanted to add, if I am not using the gallon bags for packing, I still use the same method of one days worth clothing all together. I will fold the shirts side to side in half, place pants, socks, underwear on the bottom half and then fold the top half of the shirt over the top. Keeps everything together.
Adding again. Another thing I have done when traveling where pants instead of shorts is needed is pack enough shirts for the entire trip but only 1/2 the amount of jeans and did a load or 2 of just jeans (through socks and undies in with them) mid week.
