Seriously...how old is your dd? The reason why I am asking is this. I have a dd who gets sick a lot, and EVERYTIME we have taken her to WDW...she ends up in the hospital. When she was 11 months, we ended the last 3 days of our vacation in the hospital with her (of course, I was also really sick on that trip...the Norwalk Virus left the cruise ships and invaded the park)!!
But, lo an behold...we ALSO ended up at the hospital on our last trip (dd is now 3). Good news is...we were already in their system!!! It really speeded things up!!!
So...I have been where you are, and I can second what other posters have said...the eyeglasses at Philharmagic REALLY are the least of your worries. There are so many germs, from so many people, from SO many countries....it is where GERMS go to party!!!!
If your dd has serious immune problems...I would really re-think WDW. If you decide to take her. I whole heartedly recommend having a car. The first time dd was admitted into the hospital, she was taken by ambulance from Celebration hospital (very close) all the way across town to a pediatric hospital (I honestly do not remember the name). DH had to follow in the car while dd and I rode in the ambulance. Then, he had to go back to the resort to get our belongings. Over the course of the next couple of days, he came and left (there was no where for him to sleep in the hospital room) many times. Each way was about 30 miles. Without a car, we would have spent BIG bucks on taxis.
Our dd does not have immune problems, she is just small for her age, and seems to get EVERYTHING that comes down the pike...this caused her to be hospitalized a few times during her first two years (when you are tiny, you cannot afford to dehydrate or lose too much weight). But, even with her being, by all testing results "normal", she gets sick EVERYTIME we go to WDW. There are just too many germs there that her body is not accustomed to fighting.
If you are worried enough about the germs from the glasses...I would seriously think about whether or not WDW is a good, safe place for your dd.
Just my 2cents...I'm not trying to be "pushy"...I'm just offering advice from a mom that has made hospital visits a regular part of my WDW vacations!!! I will be SOO happy the trip that we only have to visit the minor emergency center, and not an actual hospital!!!!
