I couldn’t get what types those would be fit in but in general: - train/bus stations: the biggest ones are notoriously hard to navigate, even for people going in everyday, if they ever have to choose another path. In the US I expect few of them, in EU/Asia there’s a good number of shopping mall size stations. - aeroports, as a variation of the above, although I wouldn’t download a plan just for that - government buildings / hospitals - underground malls. They are particularly harder to navigate than standard malls.
