Timed-entry ticketing, per-vehicle pricing and capacity that actually holds - from the first weekend of November to the last car on January 2.
Set slot length, cars per slot and a cut-off time per night, then watch sell-through per window fill in as the season books. When a Saturday is running hot you can lift capacity for a single slot without touching the rest of the calendar.
No contract, no monthly fee, no sales call. You pay $0.50 when a ticket sells - and nothing if none do.
