Admission to a journey or other event or establishment may be subject to paying an entrance fee / buying a ticket. A pass may give admittance without a ticket for a given time period, or give the right to obtain free tickets. A discount pass allows buying tickets at a reduced price. Sometimes a party of two or more people (either in general or in special cases such as a family) pays less than the total price of each individually. For example, a two-for-one discount means two people together pay for one only.
Admission is restricted to the available capacity, see below.
There may be other restrictions of admission:
Sometimes a person who has misbehaved is barred from admission at the same establishment, at all establishments of the same chain, or at a group of cooperating establishments. This may apply for movie theatres, swimming pools, etc. Violation may be considered trespassing.
Similarly a stalker may be denied access to some public space.
Paying for admission often ensures that one is not denied admission because of lack of capacity. However, if the time and day of use of the ticket are undetermined this may not be the case, e.g. one buys a train ticket, but the train is too crowded to enter it. Sometimes in advance the right of admission can be reserved, without fully paying for the ticket yet. There may or may not be a reservation fee or down payment. In the case of tickets for specific seats (allocated seating), etc., a reservation may also apply to specific seats. Usually there is a deadline for collecting and paying the ticket, e.g. half an hour in advance.
