I know you all at SBVR are probably tired of reading requests for a membership system and you have confirmed many times that it is on your list of planned features. I thought it would make sense to have a post about it here as well for people to post their suggestions and requests. I'll start with the things that I would love to see in a membership system.
1) A set number of free hours per month (customization to place a limit, like one per day),
2) A discount on the hours they get (either a X% off or just a flat $X amount off),
3) They can pass on a slight discount to their guests when they book multiple stations with others in a group,
4) Possible members only hours that we can plug into our store's hours chart and the booking system knows to only show those times to members,
5) Heavy discounts applied to specific hours during the weekdays, and
6) The ability to save your progress in games that support Steam Cloud Saves or the local games saved on the PC's SSD/HDD. I know this is a very complex system as devs do not have a standard of where their save file data is stored on a PC.
