Context: In a comparison test: from a head-to-head chatbot review, not a standalone agent test.

Outcome

On a 6-day family trip to Hong Kong and Macau, the PickEnough author checked AI travel advice against reality. ChatGPT and Claude were blocked by regional restrictions; of the tools that worked (Grok, Gemini and Perplexity), the author rated Grok the most accurate overall (7.2/10), with correct real-time navigation and local restaurant picks. Asked what was good to eat within 5 minutes while walking the Mid-Levels, Grok suggested a nearby egg-tart shop the author rated 4/5. Across the tools, transport predictions were within 10%, but restaurant cost estimates assumed 2 people even though the group was 4.

Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Before you start, ask me 1–3 short questions about anything important that's missing below. Keep them quick. Then do the task, checking in with me at the key points.

Goal: Act as my on-the-ground travel helper: suggest where to eat and how to get around, with realistic prices for my whole group.

What I can give you (ask for whatever's missing):
- City and the area I'm in right now
- Group: adults, kids and ages
- Budget for this meal or trip, in local currency
- Food preferences, allergies, and whether we need an English menu
- How we're getting around (taxi, metro, walking)

Rules:
- Always price meals and fares for the whole group, not for two people.
- Give 2–3 options within the walking distance or travel time I set, with how to get there.
- Flag queues, cash-only places and booking needs if you can find them.
- If a place may be closed today, say so and give a backup.
- If a site asks for a login, a CAPTCHA or payment details, stop and hand control back to me.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.
- After we eat, ask me what it actually cost so you can adjust later estimates.

Output: A short list: name, distance or travel time, expected cost for my group, why it fits, and how to get there.

You'll know it worked when: the options are close, open now, and the group cost estimate is realistic for my budget.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.

    A traveller planned a Hong Kong trip mainly with Gemini, using Grok and ChatGPT as extras, to organise locations, build itineraries, make packing lists and turn store addresses into Google Maps links. The traveller says routes were logical and personalised, but the AIs sometimes produced convincing addresses that didn't exist, and got names, opening hours or whether shops were still open wrong. Next time they'd verify every important detail on maps and official sites.
