Hi
Thanks for the interest in WooCommerce Tickets.
Unfortunately, there is no built in feature to charge different prices of tickets based on if they are a member or not.
There is a way to customize that, but would involve some coding and we can help answer some questions about it, it would be beyond the support we can provide to help out for the most part on that customization.
We try to make our plugins as compatible as possible so you have many to choose from, but we cannot recommend any themes.
Let me know if you have any follow up questions.
Thanks
