Hi, we were on the 19th cruise also and had a little visit by the virus bug. We were lucky, it wasn't until Thursday that our 4 year old came down with the the vomiting and then a fever for 24 hours then switching to a real nice cold. Luckily, I travel with the whole darn medicine cabinet on vacation since we have 5 children and almost every vacation we are on, someone gets something. By Friday he was able to atleast get back to some kind of normal but I took three of the kids (4, 8 & l0 year olds) to Doctors at home on Monday sporting ear infections for all. Just get the "family size" of amoxicillin. Other than that bump in the road, it was an outstanding trip and we are in "cruise withdrawal". It was our first, and won't be our last.
