I feel like I am becoming the lice official of the DIS.
I've been through this, and I have read EVERYTHING about it and there is ALOT of misinformation on this thread.
First of all go to headlice.org (National Pediculosis Foundation) Head lice is pediculosis. and many questions can be answered there.
Do not let this ruin your trip. If you have done one treatment iwth RID, that has killed any live bugs and even though it does not kill all eggs (those need to be combed out with a fine tooth lice comb), they would not hatch for ten days and would not become adult size for another ten. It is perfect that you are going on vacation, because you do not need to worry about your house. Lice can not live of of a human head for more than 48 hours. So there will not be any lice at your home when you return.
As far as worrying about the hotel room and the airplane, lice can only be tranmitted 2 ways. one would be if your daughter head touched another persons head and a live louse tranferred to their hair. (best way to get it) the other less common way is if your daughter laid her head on something and a live louse remained on the object and within 48 hours someone else head touched the same thing with their own head. First of all , if you already did the RID treatment, there are no live lice, so there is no risk of this. As an extra precaution, you could lay a towel or cloth over the seat in the airplane and remove and wash it when you arrive at disney. The other thing would be to lay a towel over your daughter pillow in Disney and remove it everyday and replace it with a clean one. Even if a louse was on the towel, a regular hot water wash by mousekeeping would kill anything.
Lice can not jump or crawl. They can only move if they are on a human hair. They are not an environmental concern as they do not breed in furniture or carpet as fleas do, but only can live on a head.
The only thing you need to worry about is combing through every inch of your daughter head with a fine tooth lice comb held at a 45degree angle (to scrape out the eggs better) makeing sure to drag in across the scalp (where the eggs are laid) . If you do not do this every couple of days for a couple of weeks, then an egg that is missed would hatch in 2 weeks (after you are out of Disny anyway) and would take 10 days to mature, than would start laying it's own eggs, and in other 2 weeks your daughter would be infested again (most people think when this happens that it is a new infestation, when it is actually the same infestation that has not been treated correctly. )
After one treatment, there is no risk of your daughter spreading it to anyone for at least 2 weeks, if you do not comb out all eggs however, in 2 weeks it could spread.
So basically, your good, have a good vacation and go to the source like The National Pediculosis Foundation and your pediatrician and don't get upset by people who panic and don't have the facts.
