We are a family of 4 with 2 kids aged 7 and 8 years. Staying for 4 days in Martellago for venice trips and plan to do a day trip preferably driving up ( though we are open to cheaper tours if they could go more into the mountains) to the dolomites.
Have gone through some forum topics and realized that Cortina would be the most convenient from Venice ( dont know if the same applies to Martellago). Whereas Val Gardena/Orteisi will be much more closer to the mountains and more beautiful. We could leave in the morning by 6.30-7 am. What would be a reasonably good path keeping in mind it should be easy to follow on the GPS, not longer than 3-31/2 hrs one way and which would get us reasonably proximal to the mountains with preferably a cable car ride in between for the kids and then return Martellago no later than 6-7 pm. Please advice.
