Ask HN: Map-based Application vs. classic layout

I am building a web application that allows local tourist businesses to promote their tours to tourists. When I started to develop it, I went for a map-based view, see: http://www.spotmapping.com/ Because of the map it takes a while to load the site and the content window is limited. That is why I am currently thinking about changing everything to classic web layout, with just a few pictures of the tours and a detail page, which includes just a small map. What do you think? I'm currently user-testing it with a few friends, but I wanted to get more feedback from you guys as well.
