It is not necessarily necessary to buy exclusive tickets on weekdays. This depends on the preferential policies of exclusive tickets and the specific activity arrangements on weekdays. If there are special discounts on weekdays or the exclusive ticket includes special services that can also be enjoyed on weekdays, you may need to purchase an exclusive ticket. However, if the Exclusive Ticket is only available on a specific date or time period, you may not need to purchase an Exclusive Ticket on weekdays. The specific situation needs to be determined according to the specific rules of the event.
