Context: The line to pay for parking was really short again , but we had to park on the top level of the parking structure . Waiting for the tram to come was another long wait . Usually when we go at night the wait for the tram to the park is really quick . There are more people leaving than coming , but today was different . We only went to California Adventure , since that is Brandon 's favorite side of the park .
Question: What may happen if it takes the tram too long ?
Answer:


They may walk instead .
