Beach trips are favoured by vacationers for the upcoming National Day holiday from September 1-3, according to travel firms. Travel firms have reported an increasing number of tour bookings for the three-day holiday. White-sand beaches in the central city of Da Nang and Phu Quoc Island in the southern province of Kien Giang and well-known tourist destinations in Da Lat and the northern provinces have attracted most holidaymakers. Overseas tours to Japan, the Republic of Korea and Taiwan are popular choices for the holiday. Travel firms said one- to three-day tours were mostly chosen for the upcoming holiday. Demand for tours with a customised itinerary for a group of friends or families has risen strongly in recent years. Group tours are chosen by young couples, a family with three to 15 members who love to explore nature beauty, cultural heritage sites and historic relics.- VNA
