I like how easy it was to set up, configure my pages with different templates for each event that we had going during our conference! We were able solve many issues by using this software because of its ease in use as well has being so flexible when configuring your page layouts/templates (which you can do from anywhere!).
The only thing i dislike about zapin are some elements within their website layout which could be done better or easier than what they have now - but not big deal overall since everything else works great!! It saved us time having such an efficient system at hand while managing all events throughout one calendar year!
