We toured for 8 hours with Abu Osama and Rasmi on our first ever trip to the middle east. The tour included Tarout Island and it's castle, a personal meet and greet with an excellent local artist Karieemh Al Massiri in her private home studio, a VIP experience at the Al Qatif flower exhibition, a personal tour of the maritime museum on the coast near the ruined fort, and capping off with an authentic family style eat with your hands on the floor dinner.
Rasmi was very knowledgeable about the area and its history and handled most of the talking in English. Abu Osama helped as the driver and communicating with the locals, which was at times a full time job!
Our only real complaint was that pricing could be a bit more transparent, both for us and for the guides. Essentially, plan to pay cash (SAR) up front and plan to have money available for the dinner as this is not included. Aside from that, we thoroughly enjoyed ourselves and have already recommended the tour to another American in Khobar.
