Despite the issue arising from a platform error, not the travel agency's fault, they provided thorough care and kindly took responsibility until the end, allowing us to complete the tour successfully. Since the problem occurred at the start of the tour, they upgraded us from the original speedboat tour to a pirate tour, which fortunately was very satisfying. (The following is a description of the pirate tour.) Most of the programs were self-participatory, allowing everyone, regardless of gender or age, to enjoy a mix of relaxing experiences (eating, resting) and active activities (snorkeling, trampoline, paddleboarding, diving, water slides, fishing, etc.) by choosing what they preferred. It would be perfect for families. What could have been an unpleasant experience on the first morning of our trip was handled with the utmost convenience and care by the staff. Special thanks to Guide Lee Ha-sa, who, despite having to manage so many people alone, continuously provided individual care, and Guide Nana, who was full of energy on the pirate ship. Thanks to them, we were able to start our Nha Trang trip on a positive note. Thank you!
