funny how I just found it now right before I check the forum, thanks @Sumit . this is much appriciated.

@krishnaprasad ## From admin panel booking section how many members can login at a time and book the rooms. Any number of members can log in from the admin panel and make booking separately. ## One thing observed is if one member booked the room the same room is available for booking for the other user at the same time(even its added in the cart). Thanks for letting us know about this issue. We are working on this and as soon as this issue is resolved, We will update you and provide you the patch file for this. Thanks.

Can you please share screenshots of the error

Okay, we have taken a note of that and we will make sure that we implement it in our Future updates.
