Sadly, Austria. It's a very beautiful country which I visited with my parents when I was 13. It was in the springtime and we stayed in the gorgeous little town, St Anton. One day we took a cable car half way up a mountain to an open air swimming pool, it was devine. The whole holiday was just brilliant.
I went back to Austria 20 years later, in a February - for my first, and last skiing holiday - with my nearly new husband (married for about 6 months by then and no I didn't buy him from the nearly new stall in the market!). We stayed in Bad Hofganstein in a hotel that had an open log fire, except they didn't light it for the whole of our stay. We had paid extra for a room with a balcony as I didn't want to ski as much as my husband did, who was a skier from before I met him - I had had some enjoyable lessons on a dry ski slope in England where I even managed to "juggle" my mittens during one of those lessons - so I had been looking forward to wrapping up well, and sitting on the balcony with a good book, and a steaming hot drink, while my husband skied the more difficult slopes.
The hotel management put us in a ground floor room, which obviously didn't have a balcony or any outdoor space. When we pointed this out to the hotel management they just said that they had let the rooms with balconies out to some German tourists who it turned out had booked after we had, and they hadn't even arrived by the time we got there. It was already quite late, so we couldn't speak to our rep until the next day as they weren't staying in our hotel. Nearly every local person that we met throughout our stay in B.H. seemed arrogant, and acted like they were looking down on us because we were English, and noticeably not very wealthy.
I also suffered quite badly from altitude sickness from when I had gone up one of the taller mountains to watch my DH ski down it. By the next day my whole face had swollen up like a balloon and I felt quite sick, so I had to see a local doctor, accompanied by my rep - as I didn't speak German - my altitude sickness seemed to turn quite flu like, so I couldn't even get up for about 3 days. There was supposed to be an evening sleigh ride, pulled by horses, that we booked when booking the whole holiday, but the organisers cancelled it because we were the only ones who had booked to go on it, so it wasn't worth it for them.
On top of all of that, the ski instructor who was supposed to speak English, could only say "No" and "Stop" in English, so I gave up trying to ski quite quickly (probably too quickly, but with everything else I wasn't feeling too great by then - I did not used to be a quitter in those days, so I was also disappointed with myself!)
I doubt that I am being fair in judging the who of Austria for my very disappointing late honeymoon in Bad Hofganstein, but it was the attitude of the people there that has put me off Austria for good. Oh, and even though we complained about the worst of our issues at the hotel to our rep while we were there, and to the travel company when we got back, we never got any compensation for any of our trip. By the way that was the only holiday that I have ever felt completely ripped off and disappointed by, and we are another 30 years after that now...
Sorry @travelcat, but you did ask for the reason 🙈
