As much as I love the stroller its heavy...We normally walk from the parking lots to the park and ride back on the tram to the car in the evening.
The only park where it's really an issue is the MK. At the other parks, unless you get there at a time when the lots are very crowded, it's usually easier (IMO) to just walk to the car rather than ride a tram. Even at the MK, as long as you get there earlier enough to park in the first parking lot, the parking lot is really not that far. It seems far, but isn't really.
