What is the significance of the existence of travel agencies for a growing tourist group today?

The following is the supplementary part of the question, such as the question: PART 1: What is the significance of the existence of travel agencies for today's tourist groups aiming at obtaining the best travel experience at the lowest cost? The services provided by travel agencies are nothing more than a set of solutions such as food, accommodation, transportation, visa, tour guide and insurance, or a combination of any of them. Today, however, information is readily available. For individuals, from the germination of ideas to the final formulation, a complete journey is nothing more than clicking the mouse and tapping the keyboard. From the perspective of economy and tourism experience, does the existence of travel agencies mean nothing to individuals? For example: PART2: I (Xiao Wang) am a salesman of the first-tier city 1 Travel Agency. Miss A and her party are four people, two adults and two children. In May this year, she wanted to travel to Phuket, Chiang Mai, Thailand 12 days and came to our agency for consultation. According to the investigation, our club didn't have a package tour plan for three places in May, so Miss A entrusted our club to help her plan her trip, book air tickets and hotels. So I spent half an hour making a 12-day poor travel itinerary online (without any channel of our agent). After the two sides confirmed their agreement, I entrusted my colleagues to help them book air tickets and hotels. The specific itinerary and quotation are as follows: Itinerary: 5.29: Guangzhou-Chiang Mai; 5.30: Chiang Mai; 5.3 1: Chiang Mai; 6. 1: Chiang Mai; 6.2: Chiang Mai-Bangkok; 6.3: Bangkok; 6.4: Bangkok; 6.5: Bangkok-Phuket; 6.6: Buji Island; 6.7: Buji Island; 6.8: Buji Island; 6.9: Buji-Guangzhou. Guangzhou-Chiang Mai: 1300 (children1000); (including tax) Chiang Mai-Bangkok: 1000 (800 children); (including tax) Bangkok-Phuket: 1000 (800 children); (including tax) Buji-Chiang Mai: 1300 (children1000); Total (including tax): 4,600 adults and 3,600 children; Hotel (4 stars): FURAMACHIANGMAI (Furama, Chiang Mai) Room type: Superior 400 yuan/room/night, including tax; JazzotelHotelBangkok room type: Superior room 450 yuan/room/night, including tax; Best western Phuket Room Type: Superior Room 450 yuan/Room/Night. Then the tour fee = 4600 * 2+3600 * 2+4750 * 2 = 25900 = 6475/ person's attention, and 6475/person is only the cost of machine wine. In addition: the above data are based on real data. The above is the quotation of our agent. If I go to which website, booking.com, or where to order my own machine wine? I'm too lazy to go to the movies. You can search for it yourself if you are interested. The lowest quotation is probably: 5.29 Guangzhou-Chiang Mai +6.9 Buji-Guangzhou: 1600+ (including tax); Chiang Mai-Bangkok+Bangkok-Phuket: 700+ (including tax); Maximum time: 1650+750=2400/ person; Hotel: 200 yuan can book it in Booking.com, ok? And the guest's request is that the hotel should not be too good (of course, our club mainly does high-end groups, so "not too good" is given to four-star superior rooms). But people who have played abroad know that in fact, in many places in Chiang Mai and Bangkok, you can find a room with no less than 4 stars for 200 RMB. Travel is not good, and dozens of R's can live comfortably. 200R/ room hotel can be like this; Like this; Like this; And the hotel is located within 10KM of all the scenic spots in the trip. In this way, 200 *11* 2 = 4,400/4 people; Total: 2400*4+4400= 14000=3500/ person, which is directly 3000 less than our quotation! Whether it is a few friends going out to play together, or a couple taking two children, booking tickets through a travel agency or booking tickets themselves, it is clear at a glance and cost-effective. Moreover, my client's situation (husband and wife with two children) can make do with a double room (Thailand is not so strict), which is more in line with the wishes of the guests. The above is the lowest online quotation. Of course, if you want a high quotation, you don't need to find a travel agency. Besides, the quotation I mentioned above is the bottom price! Did not increase the profit of our society! If I report it to the customer, it will not be the above 25,900 (6,475/person), but at least 27,500. I don't want to mention algorithms. Part IV: So, what I want to ask is, what is the significance of travel agencies in front of such customers? Eat? Do it yourself, I don't like what you recommended; Live broadcast? I went out to see the scenery and experience the Thai customs, and I was satisfied for 200 nights without staying in a hotel. Okay？ No, I can choose tickets from 200 to 2000 online and book them if I want. Insurance? , I buy it myself; Travel? The suggested itinerary that your Xiao Wang sent me is very good, great! Visa？ Visa on arrival, I know. A tour guide? I have no problem with language communication; If I have any questions, I will look them up in the dictionary. Attention! ! ! ! ! The machine wine reservation in PART3 and "Xiao Wang made a trip on the poor travel network for half an hour" can be done as long as he is not illiterate and has a good English level in junior high school. There should be no problem for the post-80s generation, right? Then the question comes: In today's ubiquitous information, what is the significance of the existence of travel agencies if they are faced with one or several travelers who are eager to get the best travel experience at the lowest cost? I haven't counted the shopping tours and all-inclusive tours of many travel agencies. Plus: The pictures are from booking.com, Youwan.com and Baidu.
