The best thing about this software is its ease of use, it was easy enough even as an amateur user like me could understand how everything works without any problems at all! It can be used with multiple currencies which helped us in our business because we do work internationally so having different currency rates made things easier than if only one rate would have been available -.- I had no issues while using activity manager but maybe some people may face difficulty when first starting out since there are many new users who will not know what they need from their system or where exactly should go next after logging into AM/AM Pro etc.. So you definitely don't want anyone else handling your booking process unless he knows his stuff well!! We were able book tours easily through AmPro (activity managers pro) by just entering details such as dates & places alongwith few other options required during registration itself- This saved time later down.
