I have an amateur website up and running where club members can book an accomodation.
Most other software wants more than the $100 one time payment that some random WordPress plugin demanded (VikBooking.)
Since security isn’t a concern, why not use $100 in AI tokens to build your own solution? Could then market it as a replacement to VikBooking and sell it yourself to other amateur clubs.
...and when your site is hacked, will it have been worth it?
"Some random WordPress plugin" is usually the main entry point. The core has a bad track record, but plugins are worse by far.
