Hi:
Sorry for the delayed response on our end. To make sure that I provide you with the correct information can you confirm I correctly understand your question. You would like to know that if you buy the WooCommerce Tickets plugin if it will allow users to setup and sell tickets to events they create, correct?
If so the answer is no. You are correct in the WooCommerce allows you to only connect to a single paypal account. If you have WooCommerce Tickets plugin activated it does not allow community users to sell tickets to the event. As a site admin it would allow you to setup tickets for the event however it gives a warning message to ensure that you know it is a community created event as shown in the following screenshot: https://cloudup.com/iJBeWDdHmT6
Please let me know if this answers your question and thank you for your patience,
– Matthew
