From my trip last February:
Day 1:
29,191 steps
9.21 miles
1026 calories (good thing because the night before we ate at Napa Rose!)
Day 2:
21,562 steps
6.8 miles
753 calories
Day 3:
21,301 steps
6.72 miles
735 calories
Grand Totals:
72,054 steps
22.73 miles
2514 calories burned
We stayed off-site and drove in, so no walking back to the hotel from the parks.
