Oh, we just got that this week, the night before we were supposed to leave to go visit the grandparents. Luckily we got off lightly in comparison to others in this thread, maybe the eldest and the SO and I had some residual immunity from when eldest brought it home as a toddler and we all fell like dominoes and felt like death. It was still a couple hours of no fun and a tender stomach for a further 24ish hours, and the poor little one threw up all night.
