Not as bad as some here, but ages ago, in Portugal, S coast.
We were joining several of dh's family. Arrived to find most of them ill with violent tummy bugs, very likely because the water was off for most of the day.
Staff were surly and unhelpful. Dds were 4 and 1, the younger still wanting bottles of milk. Trying to get staff to warm bottles, , or to provide something simple like toast/boiled egg, for dds, was a nightmare.
Fed up with it, dh booked us into another hotel.
Shortly before we left, I passed another room that was being cleaned, and realised that the large, locked cupboard in our room (for which we had no key) contained a kitchenette, where I could have heated milk, made toast, etc.
Had never seen such a thing before.
I asked reception why they didn't tell us that there was a kitchenette in the room - it would have made our stay so much easier.
Surly, miserable face. 'You didn't ask.'
That was over 30 years ago. I've never been back to Portugal.
The sea was bloody freezing, too.
2nd hotel was better, but didn't materially alter our opinion.
