Translation of Limonade

If I wanted to integrate the above demo on our page, would we need to work with Vocabulix or do you have some other options? Could you send me some samples of other teachers, who integrated this demo?
The bus was supposed to leave at around 4 o'clock in the afternoon, so that I still had two to three hours to organize. I went for lunch at some strange place and hardly ate as it was too ugly.
Let me understand further: If you go through the 'vocabulary builder' in the left menu and choose new lesson it works faster than when you get there through the list of all lessons? Did I get this right?
