Just got back from Disneyland and with rumors of guest Wifi in the park I thought I would do a little war walking. I didn't bring a sophisticated set up, just an android phone running Wigle connected to an external battery. Also I didn't make a point to map the entire park so this is just a sample of the first half of the first day.
As of 4/25/2017 it does not appear that Disney has rolled out park wide guest access, but the infrastructure is impressive. Again this is a very small data sample, but perhaps the 161 networks that where not broadcasting an SSID could be the pre deployed guest network. Also it looked to be a Cisco wireless deployment based on the mac addresses of the radios.
Guest network or not Disneyland has an impressive wireless infrastructure, and providing guest wifi for a property as large and as densely populated as Disneyland will be an impressive feat of engineering.
Lastly Disney if you see this post I have a suggestion for the guest network SSID.
