The car/plane ride
* If your children are in the early stages of potty training I would encourage either putting pull ups on them or having a single bag packed with extra clothes, wipes, and pull ups in it that you can grab quickly if you have to make a quick stop somewhere to use the bathroom. You don't want to have to dig through luggage if you have an accident!
* pack several snacks & drinks, in an easy to get to bag/container
* pack some hand & face wipes, sanitizer, paper towels or tissues (these can double for toilet paper if you get in a bind)
* have a bag on hand for trash as well (you can use a cereal storage container as a trash can in the car. Place a plastic bag inside as a liner)
* pack several things to keep the kids busy on the trip there & back... Things like electronics (DVD player, tablet, handheld games), headphones, crayons & coloring books or paper, seek & finds/mazes, stickers (w/an appropriate item to put them on, or they will wind up on the windows), light up toys (kids love even small flashlights in the dark), books, or Legos in a container. I think when you keep separate items for the car only it keeps them excited about access to these things on the trip. If you let them take these things into the hotel to play with they may be bored with them by the time you head home.
The beach
(I pack the following in separate "grab & go" bags & keep them handy year round for trips to the pool, water parks, etc) I prefer a bag with pockets on the outside like Initials Inc's "Get a big grip" bag, it has one handle you can throw over a shoulder or forearm, a huge deep opening, & lots of outside pockets!
* beach towels for everyone. I like to roll them up & put them in the bag last/on top, so they can be easily pulled out without disturbing anything else in the bag
* sunscreen (several types are handy especially if your kids vary in age, activity level, & depending on the activity) I like Honest brand spray & stick sunscreens
* baby powder to help remove sand. I like Honest brand powder
* flip flops. I keep some cheap pairs in one of my outside pockets. If the kids are wearing water shoes or run out barefoot (you very well may hear "ouch!! It's hot!") these are nice to have handy to switch before leaving the sand. You can rinse them off a lot easier.
*sunglasses and/or sun hats. Trust me, you & your little ones will be crying for these if they don't have any!
*small first aid kit: this you can make your self by using a ziplock bag & throw in some sanitizing wipes, band aids, Neosporin, some Tylenol, lip gloss with SPF (I always need this on hand), hair bands, & anything else you may need.
*baby wipes come in handy A LOT! Sand on hands, face, popscicles, ready to eat & need clean hands, etc.
*ziplock bag for car keys, room key, camera, money, phones, etc.. This keeps sand out, just incase!
*sand toys in a separate bag! The kids can carry this one & I usually leave it out on the balcony/deck of where we are staying. Since you can get some cool shovels & basics at the dollar tree I don't feel bad leaving them behind before heading home. Pass them onto another family checking in :)
* an umbrella.. Depending on your kids ages & how long you plan on being on the beach, I recommend an umbrella for them to play under. I found one that came in a plastic cover with a shoulder strap, which made it easy to carry.
* a blanket (one with a smooth side, so sand doesn't stick is a bonus) to keep your things on. I found one that conveniently rolls up with handles.
* my kids also love boogie boards & played on them for hours! They are perfect size & lots of fun!
For the pool
I pack about the same as for the beach, but I include goggles, arm floats, nose plugs, and swap out sand toys for pool toys!
Clothes
I've found so many times that I pack way too much clothing! Especially when we wind up shopping on our vacation! I say don't over think it... Grab a few of your favorite outfits, basics, something dressy if you plan to have a nice dinner or something (you really don't need 3 options, I promise!) & the good thing is flip flops go with anything! Also if for some rare chance you forgot something, I'm sure there's a Target or Walmart close by :)
I hope these suggestions help! I'm actually preparing for a camping trip with my kiddos for the first time & I'm sure I'll be looking for blogs with advice on what to pack! I'll be posting an update later!
Have fun!
