Hi — I'm Michael, and HotelMonitor is a one-person project run from the UK.
It exists because hotel prices quietly move after you book — often downwards — and the booking sites have no interest in telling you. Most hotels let you cancel free and rebook at the lower rate, if only you knew. So I built the thing that knows.
There's no growth team, no venture capital, no dark patterns — just a scanner that checks hotel prices around the clock and emails you when one moves in your favour.
How we verify a saving
Every deal on this site has to survive the same checks. This is exactly how the pipeline works — no marketing gloss:
Prices are re-checked every 4 hours
We scan the major booking sites (Booking.com, Expedia, Agoda, Hotels.com and others) across 29 destinations and roughly 6,000 hotels, day and night.
Every hotel is compared against its own history
A "deal" here means the price is below that specific hotel's usual rate — a rolling record of real prices we've observed for the same month and stay type. Never against a made-up RRP.
Taxes are normalised before comparing
Some booking sites quote before tax, some after. We gross everything up to a like-for-like, tax-inclusive figure first — so a "cheaper" price is genuinely cheaper at checkout.
Suspicious prices are thrown away
A rate far below anything we've ever seen for that hotel is usually a data glitch, not a bargain. Our outlier gate rejects it rather than sending you a too-good-to-be-true alert.
Savings claims are capped
Even when the maths says "−83%", we display at most "65%+" — if a number looks unbelievable, it doesn't help you and it doesn't help us.
How we make money
When you book through a link on this site, the booking site pays us a small commission. The price you pay is identical either way — we never mark anything up, and alerts go out whether or not there's a commission in it for us.
That's the entire business model. No subscriptions, no selling your data, no ads.
