Thanks for clarifying.
We have this existing “wizardry-type” snippet to rename “RSVP” and something similar could probably be done for WooCommerce:

However, I believe renaming tickets (RSVP, WooCommerce, etc) is a coming development — or at least a less complex snippet will be able to accomplish it.
So, specific to what you’re wanting, are you referring to hiding “RSVP” tickets in the back-end wp-admin event editing screen or something on the front-end?
