I know that there are a handful of EV parking spaces with chargers at each of the DW theme parks. If arriving in an EV, how does one indicate that they want to head up to those chargers to try to get a space? Do the CMs know if an EV spot is available, or are you permitted to just drive up to those spots to see if one is available? What happens if you do get up there and all are occupied? Can you just self-park into any spot you find?
