My family and friends make fun of all my little odds and ends.... until .... add in swelling music... they need something...
Here's my list...some thing go in the bags every trip, and for some items it depends on where we are traveling.
We suitcase share, in case that someone suitcase doesn't make when flying this way everyone has clean under garments, and a change of clothing or two. My daughters did not want to share... until one of there suitcase got misplaced on a cruise, thankfully the tears stopped once she realized that she had her own clothes, they found it and was at our door the next morning. No more whining about it after that.
What's in my carry on's - med's, make-up ( just a few basic's), travel size shampoo, conditioner, body wash and face wash is a must I have rosacea, and it is under control and I must have my products. A change of clothes, night wear, flip flops I never travel without these, a pair of socks for everyone ( security and mom/honey my feet are cold). Bathing suit and cover up. Hair brush and some hair gel. travel size personal toilet paper/wipes and seat covers (ever been in a stall and wished for a seat cover and there's no toilet tissue). Travel size Kleenex pack's, Travel size Lysol wipes, yep I'm the lady wiping down the tray tables, arm rest and seat belts.
2 sizes of day bags, collapsible cooler, 2 sizes of zip locks, night light, face cloth's, hand soap in the pump, power cord strip, extra batteries, rain jackets with a hood, hand wipes and hand sanitizer, I also bring my own toilet paper.

At least 2 pairs of walking shoes, for the just in case you get caught in the rain, which turns into a flooded street, and your shoes are soaking wet, and they don't carry a size 13 men's shoe in the resort gift shop... nuff said...
There are plenty of places to find Disney items, Dollar Tree, the Dollar zone at Target,
Disney store online or if you live somewhere near an outlet that has a Disney outlet...
With the ages of your girls, you might want to bring a double stroller, or rent one. My friends just did a family trip, with their kids and grandkids, Her one son did not want to deal with a stroller, which her other son joined in on.... that lasted about all of 10 minutes and they just walked to the pool and food court the 1st night, so my friend had to end up paying for 2 double strollers rentals for the week. Yep she now can say I told you sooo... priceless...
