Outcome

Asked for a central Lisbon hotel for two under $220 a night near Alfama across three October week-long windows, Chrome auto browse opened Booking, Hotels.com, Expedia and Hyatt, kept a running comparison and surfaced three candidates with trade-offs in about six minutes, stopping before booking.

Poster says:About six minutes

This is the source's own number. We haven't measured it.

Prompt Recreated prompt

The source didn't share its exact prompt, so we wrote this from what it describes.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing.

Goal: Find hotels that fit my budget and location across several possible dates.

Fill in before running: Which city and area, which date ranges, how many guests and what nightly budget?

What I need from you:
- Destination and area
- 2–3 date ranges
- Guests and maximum price per night
- Must-haves (e.g. breakfast, free cancellation)

Rules:
- Check at least 3 booking sites plus the hotel's own site.
- Compare the same hotel across dates and sites.
- Give the top 3 with total price, a one-line trade-off and links.
- Don't book.
- Flag free cancellation and total price including taxes.
- Re-check the top price just before you finish.
- Put the comparison in a table: hotel, site, nightly price per date window, total, cancellation policy.
- Check that each price includes taxes and fees.

Output: A comparison table for each date range and your top 3.

You'll know it worked when: you can open each link and see the price you were given.
