Hi Wade,
Thanks for checking out Events Calendar Pro! It does come with a recurring events feature that will let you create an event that repeats every day until a certain date. While it is not currently possible to edit the details of certain dates in the series individually, you can break them from the series after they have been created and edit the details then. As far as highlighting dates that are booked, I would recommend our Category Colors extension (free). This lets you display events with different colors based on category, so you could have categories for half day and full day.
We do offer full refunds within 30 days of purchase, so if you’d like to take Events Calendar Pro for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
