I'm looking to create an event in Express that has the option for attendee to choose the date they would like to attend. Does anyone know if this is possible? And if so, what would be the best way to set that up?
You could use an Express Ticketing event where the individual tickets are the different dates that registrants can select.

Otherwise, you will have more flexibility and customization by using a standard registration event and using either admission items or sessions to allow registrants to select their dates.
Hope this helps!
