あと「全票・半票」もわかんなかったです。
後で調べたら、値段が身長120cmで分かれるみたいですね。
要は「大人・子供」らしいです。

I also didn't understand what "全票・半票" were.

I checked into it later, and it seems that there's a price break if you're under 120 cm. Essentially, it's "Adult/Child", apparently.More directly, they mean "full fare" and "half fare".
