You print your failing query string on screen.
Copy it and execute in mysql query browser or phphmyadmin or msql prompt directly. There you will find the actual problem.

System.out.println("insert into Reservation values(" + maxResID + "," + maxGuestID +",'"+ChkPrepaid.getSelectedObjects()+",'"+txtCheckInDate.getText()+"','"+txtCheckOutDate.getText()+ "'");

i suggest building the sql query or non-query so that when it fails you can print the query and check whats happening, its usually a problem with the way the query is built.
