I like that it is easy to use, has all of my favorite options set up as well (like RSVP), allows me flexibility in scheduling events without having them conflict each other or interfere too much during times when they are not open/available etc., great customer support! Not enough time between different features available but we're working towards getting more out there soon so hopefully this will be addressed by then :) We have been able solve most problems related directly from using their services through our account manager who helps us understand how everything works together - very helpful!!
