10.1. Why Are Nested Conversations Needed?

In the booking example we discussed in Chapters 8 and 9, we might add a new requirement. Suppose a user can not only book hotels but, when booking a hotel, certain rooms may be available depending on the booking dates selected. In addition, the hotels would like us to provide in-depth descriptions of the rooms to entice users to upgrade their room preferences. This would require inserting additional screens in our booking wizard. Selecting a hotel for booking is shown in Figure 10.1.
