As a child, it had to be the last day on holiday in Corfu. We hired a boat and went to a small island. I, knowing best, refused to wear my jelly shoes in the water. Promptly stood on a sea urchin. Being the last day, my parents decided it would be better to fly home and go straight to A&E from the airport to get the spines tweezed out of the sole of my foot.
Ohh, or that time when we went to America, and I wandered out of my depth in the public swimming pool, panicked and started to drown. Thankfully, people noticed and I was rescued! Ambulance came, but luckily I was alright, and didn’t need any treatment.
As an adult, definitely Egypt. Both me and my partner had food poisoning pretty much from day one. That, and the normal stories of leering locals and attempted scams that you always hear about. The sea was amazing though - almost worth the two weeks of a dodgy tummy!
Partner’s parents are with Gigaclear. Think it’s all been pretty straightforward. They aren’t at all techy, so haven’t swapped out the router or anything. As someone else said, the supplied router isn’t great - it’s quite simple in terms of configuration. Not sure about DNS management, but I know there are other annoying things you can’t do (some config around naming two WiFi bands).
