Reserved Seating and more (i.e., like Ticketmaster)
It looks like WooCommerce Box Office does a great job of consolidating functionality of other plugins for festival seating events. It would be great to see this expanded to cover reserved seating events including seat selection on a configurable seat map with a cart timer along with group (bundle) and max purchases (i.e., functionality similar to Ticketmaster and Hold My Ticket). For us, this plugin is currently not compelling. We have more flexibility at a comparable cost using variable products in conjunction with other available plugins.
I think keep it simple... there are other solutions out there that add all the bells and whistles.
Keep it simple, keep it lean.
