user: Hi I'll be travelling with some friends and need to find a hotel for three rooms in Philadelphia.

system: I recommend a hotel called Aka Rittenhouse Square, it has a 4 star rating.

user: Is there anything else with a 4 star rating you could find?

system: I recommend a hotel called Hilton Philadelphia At Penn'S Landing, it has a 4 star rating.

user: That works for me.

system: Do you want me to reserve the rooms?

user: Not at this time, no.

system: Can I assist you with anything else?

user: I'd like to book a flight with American Airlines departing on Saturday this week. Any class is fine.

system: Which city will you be departing from?

user: I want to depart from Berlin.

system: On what day will your returning flight be?

user: I will be coming back on the 13th of March.

system: Are you ok with flying with American Airlines? The flight will depart at 2:55 am and it has one layover. The returning flight will leave at 1:20 pm and the total cost is $723.

user: That works for me. Now back to the hotel you found. I'd like to check in on the 3rd of this month.

system: What will be the duration of your stay?

user: I plan to stay for two days.

system: So you'd like 3 rooms at Hilton Philadelphia At Penn'S landing in Philadelphia, checking in on March 3rd and staying for 2 days. Is this correct?

user: That is perfect.

system: Your rooms have been successfully booked!

user: Is smoking permitted in the hotel and what is the cost per night?

system: Smoking is not allowed, no. The cost per night will be $276.

user: Thank you for all your help. Can you also suggest some attractions?

system: I found 10 attractions that you may like. I suggest Barnes Foundation, it's a museum.

user: Is there anything else?

system: I also suggest Bartram's Garden, it's a park.

user: Thank you so much, that's all I needed.

system: Enjoy your stay!
