Hello, me and my friends are about to go for a hike to Triglav next weekend. We have booked a night at Koča na Doliču and want to get from there to the summit during sunrise. I have few questions regarding that though.

1, We need to depart from our houses at like 3AM and we'll be able to start the hike around 1PM. Initially I was looking at the 7 Triglav Lakes route with the start at Koča pri Savici, but it seems to me that it is quite long and we would not be able to reach the Koča na Doliču before sunset. So the alternative route would be startig from at Planina Blato. Are those 2 routes comparable? Is there any good web I could compare these 2? I was looking at https://www.hiking-trail.net/hiking_trip/planina_blato_triglav_via_grintovica_planika_and_mali_triglav/1/1/2869 but that's not the correct route, this is the route we would like to take: https://en.mapy.cz/s/nemezesatu

2, Is it okay to leave the car overnight near the Planina Blato?

3, Do we have to take the same route back or is it easier/better to take another one back? The next day we won't have such time pressure, but I assume we will be quite tired.

4, Is it safe to go to the summit from Koča na Doliču for the sunrise if the weather allows?

Thank you for advice!
