Sure. The Marriott cyber-attack was probably one of the biggest cyber-attacks in recent memory. I'm sure there will be a larger one that comes soon, but the hotel sector really does have a reputation for being notoriously sensitive to hacks and cyber-attacks. Hotels have access to large amounts of information. When you go into a hotel, you use their Wi-Fi system and you use your credit cards. There's a large amount of information collected on customers because you want to understand their preferences and target certain services to them.
While hotels have not been considered a strategic industry, I would put them in the category of sensitive, given the amount of information that's at their disposal.
