Hi Kodi,
Thanks for checking out our plugins!
With Event Tickets Plus, you do have the option to create multiple tickets on an event and collect additional info from each attendee, but there is not currently a way to have that affect the price without some code customizations. We do not currently do these types of customizations, however we do have a themer’s guide with some great info on customizing our plugins. Also, as a premium license holder, you would have access to our premium support forums where we always there to answer questions and help point you in the right direction if you would like to take on customizations yourself!
Besides the customization though, your best bet here would probably be to set up multiple tickets, one for each variation.
I hope that helps! Please let me know if you have any more questions.
Thanks,
Jennifer
