Daniel,
I tried using Hotspots with JEvents to see if it would work, it didn't, which is understandable since you also have a events type app. in Matukio. Therefore, I have two questions.
Have you integrated Hotposts, with Matukio?
Will you be willing to integrate Hotspots in JEvents event calendar app.
I think having some kind of google map for events would probably be necessary, to tell a user visually where a specific event will be located.
All the best.
Rick Ambrosino.
