My understanding is that hotels aren't covered now, so that would be an expanded coverage. I haven't developed a full list. In my personal experience, though, I've looked at how people spend cash in big enough amounts so that knowing those amounts would help to trace either where they're travelling to or how they're spending their cash. That brings in hotels or improvements to houses for which there are construction-related costs. Those would be the two main categories I would consider.
The police, I'm sure, could add other items to the list.
