It's about £3.3 per EEA record, which is closer to $4 than $3, not that likely changes whether it seems like all that much.

The monetary value of the median hotel guest record to the sort of nefarious powers that be that scoop up hotel guest databases is ~$0. It may even be a negative amount.

The monetary value of a particular person of interest's guest record may be more than that, but those people are few and far between.

If you disagree, please let me know who I can get in touch with, who will pay me $4/guest record. I'll quit my day job, and set up camp outside a hotel lobby, recording guests and license plates.
