Marlin Tours is partly visible to agents. An AI assistant can open the website of Marlin Tours. It finds no menu or price list, so it answers from other sites. It finds a way to book or order directly, through FareHarbor. ## Direct links - Book directly: https://fareharbor.com/embeds/book/marlintours/?full-items=yes&flow=1341312 (through fareharbor acting for the business) - Phone: +351913919810 ## What to fix first - Languages: English, Portuguese - WhatsApp: a link on the site - **No tickets and prices found.** (+7 points) Agents answer 'what does it cost and when' from marketplaces instead.
