The above two flows are the only multi-step flows. The flows adapt themselves according to the user input. For eg., if the user says "I want to book a room for 2 people", the bot does not ask "How many rooms would you like to book?".
User: What are your check-in timings?
Bot: Check-in time starts at 4 PM. Minimum check-in age is 21. Please contact the reception for early check-in requests.

The flows are divided into two parts - multi-step pre-defined flows, and FAQs. I have added support to ask any number of FAQs in the middle of pre-defined flows.
