In Chapter 3, you identified use cases for the Spring Breaks R Us Travel Service. In Chapter 5, you elaborated those use cases. In Chapter 4, you identified the classes associated with these use cases. Using your solutions from these chapters, do the following:

1. Use the CRC cards technique to identify the classes that are involved in the Book a reservation use case. Recall that creating a booking involves at least a student group, a resort, a week, and a room type. Decide which class should have the primary responsibility for collaborating with the other classes and then complete the CRC cards for the use case.
2. Update the design class diagram with method names from the CRC cards. For this solution, do not try to determine entire method signatures, just the names.
