Why is the group price of seven-day hotel chain lower than the membership price?

The hotel cooperates with Meituan. Hotels with normal selling price and high profit will not buy all rooms to a third party unless the business is particularly cold (in other words, when the hotel business is bad, the rooms are empty, so lower the price and send some tourists through a third party to ensure the hotel occupancy rate); Besides, you are not a senior member, are you? Senior members must be equal to or lower than group buying, and most consumers are estimated to be ordinary members of the hotel. There must be some members in the membership system of brand hotel chains like Seven Days, Home Inns and Durian Xiaoxing who have to pay for cards, so there will be more discounts for such members!
