answer: #Person2# tells #Person1# #Person1# can book tickets for red or blue routes by phone or on the website. #Person2# also reminds #Person1# to book at least one week before #Person1# comes.
documents: #Person1#: I want to book a bus tour for the middle of June.
  #Person2#: Well, we have red and blue routes. The main attractions on the red route are the White House, the Lincoln Memorial and the Smithsonian Museum.
  #Person1#: How do I book the tickets?
  #Person2#: Well, you could do that by phone with one of our operators, or you can book through our website. Of course, you could just show up and buy a ticket the day you want to take the tour.
  #Person1#: Alright. I'll just book it online once I know our travel dates.
  #Person2#: OK, well, just remember that it can get very busy over the three months from June to August. So it's probably best to book at least a week before you come, but you still have about 6 weeks. So you have plenty of time to think about it.
  #Person1#: OK, thanks. You've been a great help.
