Is it possible to change this to max-bookings per time instead of date, and how do I add this plugin to restaurant_reservation part?

Hi Nate,
Just like what nikitae asked above, I was wondering if it's possible to change the max bookings per time instead of date?
Hoping to hear from you soon!
Thank you in advance.
Cheers,
Benessa

What I am trying to do is to create a simple "hotel booking" with allotments per day. So, basically: The user chooses a Checkin and a Checkout Date and Hotel A or Hotel B.

Now, for each day between Checkin and Checkout there are allotments, i.e. we have the following possible dates with respective allotments (rooms available):

Hotel A:
17.10.2014 - 25 rooms
18.10.2014 - 40 rooms
19.10.2014 - 20 rooms

Hotel B:
17.10.2014 - 35 rooms
18.10.2014 - 50 rooms
19.10.2014 - 40 rooms
When booking the user first chooses Checkin and Checkout, then the Hotel and THEN the script should check if any of the days in between is fully booked for that particular hotel and that particular date range and return a message that there are no free allotments for the selected date range - maybe also show which days are "problematic" (i.e. fully booked) so that the user can choose a day before or after.

What is the best approach to achieve this? I have checked several DB schemas for this and table structures, but as I said I am only finding other solutions, not exactly fit for this problem.

sir please help me

Hi @ankitkumarsah, I'm no longer involved with the Restaurant Reservations plugin. You may want to contact the current plugin maintainers at https://wordpress.org/plugins/restaurant-reservations/.
