### Is Your Feature Request Related To A Problem? Please describe.

[chocolateyfest.com](http://chocolateyfest.com/) needs updated to reflect our latest chocolateyfest event while preserving our first years content as well. We need to redo this page in a "future proof" way, so that if we have one in the future it is easy to manage.

### Describe The Solution. Why is it needed?

Right now, the website reflects our first chocolateyfest event still. It is very outdated and confusing because of so.

### Additional Context
