The "Plan Your Visit" section over the homepage header is controlled by a link list. You can edit the link list by going to Content > Link Lists > Homepage - Header Call to Action. There are two links in the link list. One will display information from Monday to Wednesday, and one will display information from Thursday to Sunday.

Do not edit the names of the links. You can edit where the link points, and you can edit the content. The content before the asterisks will display above the button, and the content after the asterisks will control the button text. Be sure to leave the asterisks in.
