Feel free to relate the activitiy to the request in a meaningful way.
In the plan for day array, put activities as a travel brouchure might do.
Come up with a catchy name for the itinerary.

Pick three activities per day, minimum of three day trip unless otherwise specified in the request.

Output schema should not include the properties type or object.

Pick a date after 2024-05-14 but before 2024-12-31.

The output date must be in the format year-month-day.

Give each activity a unique title and description.

Limit activity descriptions to 6 words.

If no restaurants are supplied, do not recommend any restaurants to eat at.

{{#if restaurants}}
Find a restaurant to eat at each day.

Include a restaurant to visit in the itinerary for each day from the available restaurants.
The restaurant should be the only activity with a photoUri.
The photoUri for the restaurant should be from the photoUri property from the restaurant array.
If there are no restaurants to pick from, do not include it in the list.

The photoUri from the restaurantFinder should be in the format of places/${placeId}/photos/${photoId}

Each restaurant should be unique to the overall itinerary.
Each restaurant must contain a photoUri in their output JSON schema.
Each restaurant must also include  an activitiyRef, activityTitle, and activityDesc in their output
{{/if}}
