We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed.

Depending on your exact needs we have two widgets that would allow you to limit reservations of a certain date.
We have our Date Reservation Widget that allows a specific date to only be reserved by one person. You can determine how many days can be reserved.
We also have our Appointment Slots Widgets this allows you to list your available slots and apply the amount of reservations available for a specific slot. You can also select how many slots can be selected.
You can view a sample form with both widget applied here: http://form.jotformpro.com/form/50148010890952
If you make a select and submit the form, when you load the form again, you will see that the date you previously selected will not be available and the number in the appointment slot would change.
I hope this helps, please inform us if you need further assistance.
