I just came back from Phu Quoc yesterday. I originally planned to go in December but there were some changes. We spent 3 days and 2 nights in the south of the island. I stayed at New World Phu Quoc Hotel, the space is really great for both adults and children. We went to the Kiss Bridge and watched 2 fireworks shows on Thursday night. You should definitely watch these 2 shows. For food, we chose to eat at the sidewalk restaurants as recommended by the locals, some dishes were a bit bad but overall it was better than other areas.
