No booking-enquiry tracking — you can't see who tried to book
GA4 fires only page_view, session_start, scroll and user_engagement — no form_submit, contact or booking event, and the single form_start from last week didn't recur. So even with 40 sessions and growing interest, not one is recorded as a booking attempt. For a rental, the enquiry is the entire point of the site; right now it's the one thing that isn't measured.
