I have private karaoke rooms, different capacity:

-room S (up to 6 ppl)

-room M (up to 12 people)

-room L (from 7-20 people) I dont want to rent it below 7 people

I have different services (they just differ by price and to which room are assigned to)

-service 1 - price for groups up to 6 people - should be able to sign up to room S or M

-service 2 - price for groups 7-12 people - should be able to sing up for room S or M or L

-service 3 - price for groups 13 - 20 people - should be able to sing up for room M or L

I want it to make like:

first group- 2 people make booking at 10  they book room S ( now room s is not avaiable as its private)

second group - 2 people make booking at 10 - they book room M (now room M is not avaiable)

third group - 8 people - they make bookign at 10 - they book room L ( now room L is not avaiable).

Now if i have first group booked - i cannot book room M at 10 anymore. Doesnt matter for 2 or 6 or 10 people.

Thanks in advance,

is there any way you have some sort of chat?

Thanks
