Is an event an attraction? Is something like the Edinburgh Military Tattoo an attraction? Are the Olympics? The varying scopes of attractions.
Attractions can be the prime motivation for travel to a destination. They can be a secondary reason for travel or as a stopover. How many have navigated Route 66 in the US, only to stop over and visit some of the many curiosities along the way.
Time is relative. It can span a good amount or very little. The reasons for any visitation depends on the individual or market segment.
Who owns the attraction? Who is the governing body that manages the attraction? This may dictate prices or fees for entry. What is on offer or not? Will it be profitable or non-profit.
Attractions can be classified as having various degrees of permanency. Are they a permanent fixture in the landscape? Or is it just a building, that the exhibits are the attraction and can be moved from one place to another.
The Olympics and the Military Tattoo have a short duration, and can be moved from one place to another. They are events. Though there is some permanency by fixing it within Edinburgh. The concept of Military Tattoo can exist in other cities, but there is only one Edinburgh (Scotland) Military Tattoo.
But an attraction such as the National Football Hall of Fame has both fixed and movable permanency. The exhibits are the attraction and can be moved if they outgrow their current housing. The building, though a wonderful piece of architecture, is permanent, but can be repurposed if necessary.
So, attractions can be classified by the various degrees or scopes. I have just touched on a few here, and yes, they can be a matrix of complexity.
Complexity in that they can have scopes of permanency, cultural, and type of facilities. That leads into the discussion of how do we measure success. A question for another day.
