Appointments+

Our appointments are 10:30am-12:30pm; 1:00pm-3:00pm; 3:30pm-5:30pm;  6:00pm-8:00pm & 8:30pm-10pm. The time base needs to be 30 minutes because there are multiple 30 minute breaks in the day to clean the bike(12:30-1pm, etc) All tours are 2 hours with the exception of 1 tour which is 90 minutes (8:30pm-10pm) How do I go about setting this up? Looks like only 1 break can be scheduled per day. Thanks
