Marriott Rate Finder

About

Marriott Rate Finder takes the guesswork out of corporate travel booking. If you have access to multiple Marriott corporate codes, finding the cheapest one for a specific hotel and date is normally a tedious, manual process. This extension automates it entirely.

How it works
Navigate to any Marriott hotel search results page, click "Find Best Rates", and the extension silently replays your search once per corporate code — comparing prices across all your codes simultaneously. Results appear in a floating panel alongside the page, sorted by distance, price, or savings.

Key features
  - Multi-code scanning — test as many corporate codes as you need in a single click
  - True cost comparison — mandatory destination and resort fees are included in the rate so you're always comparing apples to apples
  - Savings at a glance — see the percentage discount versus the standard rate for every hotel
  - Expand any hotel — click a code chip to see what every one of your codes would charge for that property
  - One-click booking — the Book button takes you directly to the hotel's availability page with your best code pre-applied
  - Filter & sort — search by hotel name or code, sort by distance, lowest price, or best discount

Privacy
This extension operates entirely within your browser. It replays your own search requests using your existing Marriott session — no data is sent to any third-party server.

Setup
Click the extension icon and enter your corporate codes (one per line). Then go to marriott.com/search, run a search, and click "Find Best Rates".
