The poll says to put in a ride. It doesn't specify any particular one. It could be the Disneyland version, the Disneyland Paris ride, or something entirely new.
SpectroMagic is usually run on Saturday only. Wishes is shown on Saturday night and maybe once more during the week. IllumiNations and Fantasmic are shown every night.

1) There are usually several ice and vending machines on each floor of each building at each resort.
2) Yeah, the buses for Downtown only run between resorts. It can be kind of annoying. Does anyone know why there is no transportation between the parks and Downtown Disney?
