World Elite Kids uses Events for various bookings. From their home page under "Events" you choose "Event Calendar" which takes you to their Event Calendar which they embedded nicely into their own webpage. View their Event Booking page here. (You may need to scroll to the next month to see all the options, and notice how much easier it is to read the ones with light colored backgrounds than dark backgrounds).
American Twisters hosts birthday parties every weekend. View their party webpage here. As above, their webmaster has embedded the calendar directly into the bottom of the page using an iframe. Notice they give all the party details in text at the top of the page.
