It depends a little bit on your setup...
If you extended the BookingObject class with a description, you could use a data control like a Repeater to present the data. Similar to how the drop down list is built (possibly with the same data source) you can bind that Repeater so it shows a list of the available BookingObjects. Each BookingObject has a unique ID which you can use to create the popup.
If you add a HyperLink or another control to trigger a popup, you can forward the unique ID of the BO to the popup. Inside the popup, you can read the ID from the query string, and then call GetBookingObject on the BookingObjectManager class to get the details of the BO.
Does this help??
