If they both healed in 11 days and your daughter did not take antibiotics that tells you it was not bacterial but viral. Could have been food or drink or maybe even ammune system. Who knows...always a crap shoot. Our solution is to drink heavily to kill everything. Fireball seems to be a real helper. I like 6-10 shots per day.
Sickness has gotten better but post Temptation depression syndrome has set in ..... we're planning our next trip in hope of treating symptoms.
Everyone is different of course, but flying can be a big contributor. Someone mentioned probiotics earlier... Yes, many say eating a couple of yogurts a day for a week before the trip works well to combat bad bacterias... Real yogurt though, not the fat-free ones that are just sugar. (Hubby here... I used to work in South Asia, and the yogurt thing worked well for me on several occasions flying back and forth.)
We brought Lysol and hit the vents in the riom a couple times in the recommendation of others. Dint know if it help but no illness!
My husband and I were at Temptation this past July. It was our maybe 7th visit there. However, it was the first time we got sick and both of us were affected. My husband passed out and had trouble regaining consciousness. It was a very frightening experience: his eyes rolled back and I had to remind him to breathe. Many people might think it was from "too much" alcohol, but it happened in the early afternoon and we had only had maybe 2 drinks by then, nothing too strong. We both ordered the same drinks but when I washed out our Bubba mugs, my drink was clear and his was dark pink. We suspect someone tampered with his drink. As for me, I had stomach issues the final 2 or 3 days. I threw up after almost each meal. I thought I might have had a stomach virus but I was had no issues once back in the US.
Same with Breathless Punta Cana - I couldn't get over how gross the glasses were and they basically just rinsed them - BARELY!!
Out of 8+ trips to Mexico there was one trip where I thought I would try an stay hydrated by drinking a class off water from the bar with every drink I got. Well something got me and bam I could not be far from a toilet for the next 3 days and no medicine would touch it.
I was just there, for my first time, earlier this month and came home the same way. Glad it wasn’t just me!
I just got back from Cabo. After 12 hours back home I started to feel sick. Bad cold symptoms. Been like that now since Tuesday.
