My immediate reaction to this is, "holy crap!"

Using a 12MP camera, each image you take would roughly be 2-3MB. Assuming the higher end of 3MB (and only 230GB available per card), that's ~79,000 photos per card.

Since "a few" typically means three or more, let's assume three, that's ~240,000 photos. If it's a typical holiday/vacation, that's likely 2-3 weeks -- let's assume it's three, which comes out to be 21 days. Achieving ~11,000 photos per day during a holiday is quite a feat...

I'm pretty sure they are taking a few 4k 60fps videos as part of that holiday, and those eat space like it's nothing.

More rough napkin math...

A second of 4k60 video is ~7MB, but we'll overestimate to 8MB (though I'm using really rough metrics here). At 690GB (230 x 3), that's ~86,000 seconds. Or, more familiarly, about 24 hours of 4k60 video (holy cannoli, Batman!). I guess that's about an hour's worth of video recording every day over a three-week period. Understandable, and more doable, though still really excessive.

And when you turn it into a more realistic scenario (~1 hour video/day - something I'd almost never do with my iPhone but often do with my Pixel), it's hard to imagine not having access to WiFi throughout the week. Even the hotels/apartments with really poor connection seem to have no trouble uploading the photos/videos throughout the night.
