We have been asked that for a few of our events we have a range of time that they are purchasing a ticket for versus just a set time. Having this option would help our organization.
Example: Museum Admission is currently selling for only a 10am ticket but we don't take admission by timed tickets we allow guests to come any time that day. So if their admission ticket told them that is was a day pass or good from 10-4pm, that would be useful. Having all tickets say 10am on them has caused confusion.
Another example is when we sell rides on our helicopter, we would like it to be a ticket for 10-12pm or 1-3pm or so on and not 10am, 11am, etc.
