we plan to take the Alta Via 1 trek from Dobbiaco to Belluno between July 27th and August 3rd this summer (starting off in Dobbiaco on 27. 7. and getting to Belluno on 3. 8.). We have planned for the trek in advance and contacted the huts to make the required accommodation reservations beforehand (it is 4 of us + a dog).
We're planning to arrive to Cortina d'Ampezzo on Saturday Jul 26th, sleep there and travel from Cortina to Dobbiaco on Sunday morning (taking a Cortina Express bus) to start the trek by Lago di Braies. Similarly on the last day, our plan counts with reaching Belluno and then travelling from there back to Cortina (this time actually taking a Dolomitibus to Calalzo, and from Calalzo taking another one to Cortina). We want to leave our car somewhere in Cortina for the time when we will be on the Alta Via.
The question I'd like to ask is where would you recommend us to leave the car in Cortina for those 8 days? I was kind-of reluctant to leave it on an unsecured parking lot for the whole time, so my thinking was to either book for a night on Jul 26th at a hotel somewhere in Cortina and agree with them to have the car left there until next Sunday (however we've emailed a few hotels already and this does not seem to be the easiest option) or camp in one of the campgrounds in Cortina and similarly leave the car inside a campground - but one of the campgrounds already replied back they are fully busy throughout this period (surprised me a bit as we're in the Dolomites 2 years back for a 2 weeks trekking vacation in second half of August, and never have we had a problem with fully booked campings whatsoever...). But I guess this is even more high season...
Please is there any attended (e.g. underground) car parking lot in Cortina? What do you think would be the best option for us?
Many thanks in advance for your advices and hope to meet you in the Dolomites :-)
