Prysm — True Total hotel pricing

About

Prysm — True Total Hotel Pricing

Hotel booking sites show you a nightly rate, but that's rarely what you'll actually pay. By the time you reach checkout, taxes, resort fees, destination charges, and other mandatory costs can inflate the final bill by 30%, 50%, or even more. Prysm fixes this by showing you the true all-in cost of every hotel right on the search results page — before you click, before you compare, and before you book.

How It Works

Prysm runs quietly in the background as you browse hotel search results. It reads the displayed price on each listing, identifies any taxes or fees shown on the page, and fills in the gaps with conservative estimates when charges are hidden. The result is a bright, easy-to-read badge on every hotel card showing the True Total — the realistic price you should expect to pay for your entire stay.

Hover over any badge to see a full cost breakdown: base room rate, taxes, estimated resort or destination fees, and any must-have extras you've selected. Everything estimated is clearly marked so you always know what's confirmed and what's approximate.

What Prysm Catches

Mandatory resort and destination fees that many Las Vegas, Hawaii, Florida, and New York hotels charge per night but bury in the fine print
Local occupancy taxes, city taxes, and tourism levies that vary widely by destination
The gap between the advertised "per night" rate and what the full stay actually costs with all charges included
Supported Sites

Prysm works on the most popular hotel booking platforms: Booking.com, Expedia, Hotels.com, and MakeMyTrip. Enable any combination from the popup settings. Adding more sites takes one click — Prysm requests only the permissions it needs, when you need them.

Live Currency Conversion

Traveling internationally or comparing prices across regions? Prysm converts every True Total into your home currency using live exchange rates updated throughout the day. Choose from USD, EUR, GBP, INR, JPY, AUD, CAD, SGD, or AED. Switch currencies anytime and every badge updates instantly — no page reload required.

Sort by What You'll Actually Pay

Hotel sites sort by the advertised rate, which hides the most expensive properties behind a deceptively low sticker price. Prysm adds a one-click "Sort by true total" button that reorders results by real cost so the genuinely cheapest option rises to the top.

Must-Have Extras

If you always need breakfast, parking, or Wi-Fi, toggle them on in settings. Prysm adds estimated costs for these extras into every True Total so you can compare hotels on a level playing field — including the things you'll pay for regardless.

Privacy First

Prysm runs entirely in your browser. It does not collect personal data, does not track your searches, and does not send your browsing activity to any server. Exchange rates are fetched from a public API; everything else happens locally on your machine.

No More Checkout Surprises

Stop comparing hotels on incomplete prices. Prysm gives you the honest number upfront so you can make smarter booking decisions and never be caught off guard by hidden charges again.
