These are counts of what our own checks saw (about every 15 minutes); an opening that appeared and was taken between two checks is not in them, so treat every figure as a floor.

Watching since Jul 27, 2026. Our shared checker refreshes about every 15 minutes — that is the measurement; your watch is the alert. A free watch checks every hour; a Priority Pass watch checks every 5 minutes. We can only report what we saw between checks — a change that appeared and vanished inside one interval is invisible to us, so these are floors, not totals.

Of the 19 nights we saw open and then close again, 21% were gone within an hour of us spotting them, 74% within six hours and 89% within a day. These are counts of what our own checks saw (about every 15 minutes); an opening that appeared and was taken between two checks is not in them, so treat every figure as a floor.
When do cancellations show up at Platte River?
62% of the nights that opened were Friday or Saturday nights.
How fast are alerts?
Free: we check every hour, day and night. When a site opens for your nights you get an email with the booking link in it. Priority Pass is $10 once, not a subscription. For one watch, for as long as its dates are open, it checks every 5 minutes instead of every hour, so you hear sooner. A free watch checks every 60 minutes, and a site can open and be taken between two checks.
How many campgrounds can I watch?
As many as you like, on one email address — every campground page has the same form. Each watch is separate, with its own dates and its own one-click stop.
What does it cost?
Watching is free — no card, no account. Priority Pass is $10 once, not a subscription. For one watch, for as long as its dates are open, it checks every 5 minutes instead of every hour, so you hear sooner.
Does it book for me?
No — you get the booking link the moment a site opens; booking stays in your hands, on the reservation system's own site.
How do I stop, or change my dates?
Every email has a one-click stop link. A watch ends by itself the day after your last night, with a note on what it saw. For new dates, subscribe again on the campground page — it takes ten seconds.
