You can reserve the training center and agility barn if the spot is open. Registration is for for half an hour intervals and you can book consecutive windows if you want longer rental period. If a block of time is open for booking it would be clickable and you can select "Drop in" and pay. If a block of time is not open it would be crossed out. 

Note: that the system will ask you to choose ONE dog when booking, however, you can bring as many dogs as you want during your rental.
