The Advantages 

Reducing the in-field signage, reduces set up costs of sign production, and also reduces the ongoing maintenance costs of the experience, caused by vandalism or weathering of sign materials.

Ease of information updating. Rather than having to create all new signage when something changes, information can be updated simply by updating the website content. This allows the parks managers to easily keep up with trending visitor attractions.

Broadened demographic. Traditional signage displaying large amounts of written information, limits the audience to those with higher literacy levels, and/or good vision. By providing the bulk of the information
via audio file, the experience then transcends the visual barriers, additionally allowing the visitor to look and wander around the location at the same time.

Engaging younger generations by using modern technologies to which they are keenly familiar.

Information can be delivered in a form which is more entertaining, and thusly, more likely to be absorbed and retained. 
     
The possibly of transmitting more knowledge and information than traditional read signage as the boredom factor doesn’t weigh in as early.
        
A share experience - listening together rather than reading in turns helps to create a shared experience amongst
visitors.
       
A moving experience – it’s often hard to stop, and read, on an enjoyable walk………
