Naples looks like a city best explored on foot, but I'm also considering Hop On Hop Off Naples (https://www.hop-on-hop-off-bus-tours.com/tour-city-sightseeing-naples-hop-on-hop-off-bus-tour) for convenience. Has anyone compared both options? I enjoy walking and discovering hidden streets, but I'm worried about missing out on major landmarks or wasting time figuring out routes. These Naples bus tours seem like a good overview of the city, especially for short stays. Do you think it's better to use the bus first and then explore specific areas on foot, or skip it entirely?
