How to add multiple prices for Events

Some of the events that will be listed in our directory will have multiple ticket options, such as depending on membership status of the attendees, ie members vs. non-members. It appears the field will only allow number and decimal. We want our users to be able to add text, numbers, semi-colon, commas, and $ sign as needed. How can we achieve this and make event entry simple, streamlined and consistent? We are still in dev mode.

It might be something like this:
Saturday, April 27th – $55; Sunday, April 28th – $45; Both Days – $65

We tried both the Price Range and Event Registration Fees fields and neither seemed to accommodate our needs.
Thanks!
