South Tyrol, Italy - Dolomites Hiking trip, Venice tour (optional)

Short trip idea:
3 hikes in Val Gardena area, 1 day Bolzano tour, 3 hikes Misurina - Cortina area, 1.5 day Venice tour ( optional)
Our transportation will be rent cars ( ideally 4 travelers per car), so if you decide to join this trip let me know if you open to be carpool driver. Remember you'll need to drive on narrow mountain roads.
For now I have 2 people that will be carpool drivers, so we can cover extra 6 people. But your accommodations must be close to driver's accommodations plus your flight schedule must match.
If you decide to join then you have to book accommodations . Only after I'll give you RSVP. If you never hiked with me you have to join my one of my Sunday hike .
The easiest and maybe the cheapest commute is fly to Venice and rent car there. It is 3.5 hour drive to our first destination.
Our start point will be town/village Siusi ( Seis am Schlern in German), it is a place of largest alpine meadow in Europe. We all must be there Aug 21 before 7pm. We'll stay there 5 nights.
