Thanks so much for reaching out and for your interest in our products!
First of all, you are welcome to apply for our Nonprofit Partnership Program, which will grant you free access to either Events Calendar PRO or Event Tickets Plus, though without premium support access.
With both Events Calendar PRO and Event Tickets Plus, you can have customers purchase tickets for events that span a number of days. It is worth noting that Event Tickets Plus does not support recurring events at this time, however you will still be able to achieve the results that you are looking for by setting up each event separately, or by creating a series and then “breaking event from series”, so that you can easily populate your calendar with events, and still use the Event Tickets Plus features.
Also, please feel free to check out our demo site here.
Please let me know if you have any other questions on this topic!
Thanks,
Jaime
