Wow, really? Ive heard that there is a certain time when to go before all the 'chavs' turn up. I went last year, but as you probably know, it was a snow blizzard (well for the time I was there anyway), so cant imagine there was too much stupid behavior afterwards.
Its such a stunning place, so its a shame people ruin it, and yes, I can understand why the locals hate us - perhaps if people actually cleaned up after themsevles and enjoyed it for what it is, there wouldnt be that problem.
It looked like people were being fined left, right and centre by the Police this year too! (from what I saw on Social Media!)
I didnt go this year due to other commitments, but also felt id leave it a year before going again so the novelty doesnt wear off! Kinda gutted I missed this year though. Perhaps next year now!
During the snow blizzard, we decided to drive to Venice one day after breakfast as it was 26 degrees there and only a 2 hr drive away - that definitely made the trip for me I think.
Grossglockner High Alpine Road is also worth the journey for stunning views up in the mountains!
