• 1 medium rolling bag for Lissa's clothing (Here is the set we have)
• 1 small rolling bag for Shawn's clothing (Here is the set we have)
• 2 small hard-side bags for Knox, Liv, and Lucy's clothing (Liv's bag similar, Knox's bag was the smallest of this set)
All of our luggage bags had expandable zippers which were super important because we really packed the small ones down! They worked like a charm, and I found that I really prefer the hard-side bags to the fabric ones.
• 1 backpack/bag for each person
Our backpacks were our carry-ons and all had a little something different in them.
Shawn's backpack (also carried our laptop, important paperwork, and DSLR camera)
My bag (this is typically my camera bag, but the lens insert and pockets worked really well)
Knox's backpack (iPad, headphones, activity books, pens/pencils, small toys, change of clothing/underwear, water bottle and snacks)
Liv and Lucy's backpacks (these are smaller sized so it meant they could carry them by themselves which was essential at a few points!) I packed Lucy's backpack in my larger luggage bag on the way there. Liv's bag included her iPad, headphones, small zipper bag of shopkins, coloring books/activity books, crayons, stickers, wipes, extra Pull-ups, water bottle and snacks)
• Stroller (ours has been discontinued, here is a similar)
I debated on bringing a stroller, but ultimately it was SO helpful- especially in the airport and on a few sightseeing days. We needed it most for our 3 year old (we carried our new daughter in a carrier most of the time). I would recommend buying one there if you are not bringing other children with you, and I also would not take a stroller that is too precious to you. There were a few moments we weren't sure if we'd see it at baggage claim, and in those moments I was really glad we'd brought our old umbrella stroller.
• Tula Carriers
Not technically baggage, but carriers. :) We borrowed my sister's Tula and so we had two- one for each girl. These were so great- especially on the days when the stroller wasn't appropriate (hiking the Great Wall, for example) and we were SO glad we'd brought them. We love our Tula- very comfortable and fit our 2 and 3 year old well.
• Compression Bags
I bought these on a whim and they were so useful for us. I had seen a lot of recommendations for packing cubes, but they were more expensive than these bags and the compression aspect of the ones we used was great for diapers and clothing.
• Money Belt/Neck Wallets
Shawn and I wore these money belts from the time we took off in Lubbock to the time we landed back home (well, I guess we took them off while showering and sleeping, but you get it). They were fine, necessary, but annoying. My dad had a neck wallet- something I didn't even know existed- and I will definitely be purchasing one for our next overseas excursion because it seemed way more comfortable.
• Luggage tags
This might be an obvious, but I wanted to pass along a few tips. Make sure that every piece of luggage you bring (including carry-ons) has a luggage tag on it. We like to fill out the address with our home address and then put another card with our name and our hotel's address ON TOP OF IT for the flight over. We do this on trips longer than a few days, when there would be enough time for our bags to still arrive at our destination should they be lost or not on the correct flight. Once we receive them at our destination, we take the top tags off, so that our luggage now reads our home address.
Another thing to consider is your personal safety. We are very careful about what we put on our tags, since anyone can see that information. We only use 1 name, address, phone or email for all of our bags, and on the kids' backpacks, we even flipped the information over and wrote "over for info" on the card- just to ensure that wandering eyes couldn't associate our children with any address or name. We were also careful to make sure that the bags they were carrying did not have their names displayed on them (the girls' backpacks do have a monogram)- this is just a safety measure to prevent strangers from knowing their names.
