I think this happens to every family at least once when you take vacations.
Our second trip to Disney my youngest got hit with the tummy bug, was in the hotel for 2 days. 3rd day she was in the stroller all day (she was 6 at the time) and the same trip my oldest got a head cold. she's get a nasty sounding cough that doesnt bother her but sounds horrible. we'd be standing in lines for rides and she'd be hacking and people around me were looking at me like "get that kid out of here lady!" it was a rough trip
we also missed
MVMCP because the two of them were sick. that was rough and rough on the middle child who was healthy and had to miss out
and the last time we went I had some crazy stuff happen with my legs. I think it was a combination of my shoes being too tight along with the horribly humidity but my legs were killing me after our first day there (we flew in and spent 1/2 the day in the park that same day) the next day my lower legs looked very veiny to me but I ignored it. trying to sleep night 2 I was in horrible pain in my legs
morning of day 3 my legs hurt bad and my sister says "did you bruise your leg or something?" the whole lower part of one of my legs looked like it had one huge bruise on it! the other leg looked very blueish and veiny
it was CRAZY! I went back to the hotel and put my feet up iced my legs and searched online
it appears that it was just from my feet having swelled and my shoes being too tight to compensate along with the humidity and walking so much more than usual that caused it
I was freaking out. Every day I had to take afternoon breaks to go back to the hotel to elevate my feet and ice my legs!
Next trip I'm wearing flip flops on the plane (in case feet swell) and being sure my sneakers are quite loose!
