If a client has a dog kennel and wants to be able to have people register their dogs when they need them kept could DT Register work? If they have spots for ten dogs when they are full it would need to show them. The biggest thing would they be able to pick their days, they may need it boarded for Monday thru Wednesday. Don't know if this would work but thought I would ask.
I would suggest setting up an "event" for either a week or a month of boarding date options. You could then create a custom field where the user would select the days that they need. This would likely be checkboxes. You can assign a fee to each box so the price is calculated based on how many days are chosen. You can also set a limit to how many users can select each option in the field. For example, only 10 people can choose Monday.
DT Register is intended for event registration, but many people have used DT Register for situations like you are describing. Thanks.
