I won't tell you what we forgot to pack, because I can't remember, but here are some things to not forget:
Duct tape - roll a fair size amount onto the end of a pencil or pen, to have handy - you never know when you might need it.
Safety pins
Night light for room
Extra power bar if you need one to charge phones/netbooks etc.
Dollar store plastic capes for riding on splash mountain
sunscreen
TAKE A PICTURE of a piece of paper with your name/phone number on it, so that if you lost JUST your memory card, someone might be able to track you down.
LABEL all electronics with all contact info.
TAKE A PICTURE of all luggage packed and leave it on memory card in camera so that if your luggage is lost on flight, you will have a fresh and neat photographic list right on you (camera goes in carry on!)
Take all prescription medications in a carry on and make sure to take a few days extra with you, in case you couldn't make it back. KEEP it in the original, labeled container as well.
Pack first aid medications and what not - bring polysporin, BenGay, muscle relaxants, gravol, stool softener (colace) in case anyone gets constipated which is not fun! cooling foot lotion, blister bandaids, MOLESKIN, (moleskin is a blessing for blisters, oh my gosh!! I used it on blisters on the bottom of my feet over top of bandaids, and it padded it enough to be able to walk on them.) reg. bandaids, advil, tylenol, heartburn medicine such as tums, eno, cold medicines/antihistamines if you plan on taking decongestant before plane ride, HAND SANITIZER for in the parks, etc.
Vicks inhaler is nice for on plane, you just sniff the vicks inside, and it can help to decongest.
Nasal spray like otrivin for on plane, you can use it to help decongest.
Polysporin eye/ear drops if you want to make sure if your eyes are sore/irritated OR for use after swimming if you get water clogged in your ear, etc.
Swimmers drops for ears, to help dry out water? Water wings?
BUY and use earplanes if you are flying, (can buy them in airports, pharmacies, etc.) they are a GODSEND for kids and adults - I used them when I had a horrible ear infection that Dr. said I shouldn't fly, and it was a miracle that my ear drums didn't burst, IMO, but it was thanks to the earplanes. Put them in and wear them the whole time, I swear by it. I always had ear trauma before I found them, not anymore.
Ring pops - some people like to 'suck' on a lollipop when landing on a plane, they say it is better than a chewing gum motion.
Cool gel pack - could be used to cool down hot tired feet at night!
