We have a trip booked for the first week in February, but now I am rethinking this as I am terrified of our two year old catching the flu. Thinking of pushing until the first week in March, crowd predictions are still low and prices about the same. Anyone have any advice or insight into this? Any pros or cons to going in February as compared to March? TIA!
I'm pretty sure one can catch the flu (or any virus) just as much in March as in Feb. For that matter, one can catch a virus any time of the year. My youngest son caught the endovirus the last week of May 3 years ago, just before Memorial Day, which landed him in the hospital for four days and made him miss his last week of Kindergarten and also happened to be 3 months AFTER we came home from a 10-day WDW vacation. The endovirus is VERY similar to the influenza virus, except you get to constantly throw up, too.

yay!
The better thing to do, would be to practice good hygiene. Wash your, and her, hands often, use hand sanitizer, and most importantly, teach her to not touch everything in sight, run her hands all over everything as she walks by (a habit my kids STILL have not broken and it drives me CRAZY!!!! LOL), and keep her hands out of her mouth and eyes. Also, the week or two before the trip, limit contact with public germ magnets (like playlands, indoor parks, birthday parties, family get-to-gethers, etc) and be extra careful around anyone who is sick.
This is reminding me of the first time we went to FL with the kids - they were 11, 7, and 6 and it was pouring rain so we stopped at an Oasis on the Tri-State Tollway in Illinois. There was a McDonalds playland there and my kids made a bee-line for it. I swear everyone in the entire place stopped and stared when I screeched "NOOOO!!!!!" All I could see if them picking up some virus on day 1, coming down with it on day 4, spreading it to each other the rest of the week, and having to drive 26 hours home on day 10.
Nightmare city!! LOL
Just be careful in the weeks leading up to your trip and practice good hygiene while you are there, and you should be fine!
