Hi everyone,
If you are working on WIX Booking systems, you are probably aware that when a user log in as a member and want to book something, lets say some class, they can choose the date on the calendar, click on the time and then if the class or booking of any kind is “full” – it will show that this time slot is full, but until that point, there is no way for the member to know how many other people are in class, or to put it in other words, how many spots left in any particular class.
See, from a UX point of view, if a member knows how many spots left, it might affect their decision making in choosing to book at that moment or not. If the class is almost full and there is only 1 spot left, the member might quickly book their spot to secure it. Vice versa, if the member see that there is only 1 person booked for that date and the class is tomorrow, they might consider booking or not, depends on how they like the class to be in terms of amount of students. If they like small class and they see that tomorrow class is almost empty, it might just be a factor in their decision making.
Overall, knowing the class or any booking “Participants” parameter is crucial - and this parameter is available for the website owner but invisible to the site members - therefor, I would like to suggest this feature for a #FeatureRequest 
vote.
It might look like a little thing, but from a UX point of view, this is “yuuuge” factor in a user decision making process while using a booking system.
See the shot below with my suggestion for placement of this feature.
