Hi Tim!
Thanks for reaching out to us! I’d be happy to help you with that.
You can certainly achieve that with some custom coding. We don’t recommend you alter the plugin’s code because you’ll loose all the changes when updating the plugins.
I know one our team members is currently working on building an extension that will add a field in the Tickets settings where you’ll be able to put a custom URL to redirect users after they RSVP.
I will reach out to him and see if I can get you something already working for you to use.
If that’s not possible, I will at least point you in the right direction on achieving something like that.
Please hang in there.
Thanks,
Victor
