The tour went smoothly from the bus from Hanoi Hotel pickup until the end. The agency texted me by WhatsApp and communicated clearly about what to expect and do.
The overview says the cruise is to Ha Long Bay, but the route depends on what cruise the agency is able to book. For my trip, we went on Renea Cruise to Bai Tu Long Bay. The cruise cabin was clean, beautiful and comfortable, and has windows for looking at the scenery. Take note, Ha Long Bay has a no-plastic water bottle policy to protect the environment, and cruise provides free drinking water.
The cruise has amazing once-in-a-lifetime scenery. The tour guide, Duc, was excellent and communicated very well about the information on the Bay and our itinerary. Activities include kayaking and swimming in the Bay near some beaches, squid fishing at night, and cave exploration. The food was decently prepared too. Halong Bay was the highlight after the busy night in Hanoi.
