I have edited the Renaissance Festival official map to remove all the extraneous information and left only the useful information related to the wedding.
Important areas are highlighted by the large red areas with the thick black borders.
As you will see, the entire grounds are represented, but from the entrance (marked Enter Realm) there is a convenient red arrow line that outlines your path to get to the wedding chapel (named Canterbury Chapel)
You will gather at the chapel starting at 10:00 am and the wedding will begin at 11:00 am with the bride being escorted to the chapel.
Once the wedding is completed, you will make your way down the remainder of the arrow (it’s a nice downhill walk) and arrive at the Royal Gardens. You will show the second of your tickets to gain access to the reception area where free food, lemonade and beer will be served. Oh and the cake stuff will happen there too. Did I mention the free beer?
There is also an cash bar if you would like something different than the Bluemoon beer provided.
