This is the best calendar suite out there. I run a small site for an association with 300 members. Here's what we've tried, and why we ended up with Events Calendar Pro:
We used Time.ly All-in-one event calendar ... which slowed down the site and was buggy, and had plugin conflicts. The default install also confuses google crawls. Also very poor support on their forum. They can't even update you on what is going on... for example 'they are working on Time.ly version 2.0' and 'we'll keep you updated' ... no updates in the last 5 months on that blog post. Zero credibility. Their plugin also crashed our entire site back in August as part of an automatic upgrade. This happened to many other people too. Time.ly's response was to DELETE the forum postings from users. Timely use their own forum for a reason ... to maintain editorial control.
We tried IgniteWoo Events Calendar & Ticketing ... which is very basic and costly. IgniteWoo are not too quick on providing support either, but were better than timely.
Events Calendar + PRO may cost a few $$, but well worth it. The team at Modern tribe have been quick to respond to queries. What's most important is that it actually works. The WooTickets module is great too - because it works!
