Set Amount of rooms and types available on specific days

In the back end – a place to set room types avalable for specific days

This must be done for a couple of years for advance booking

It must be easy to set the whole year(s) and able to change 1 day if necesary.

So if a hotel has 100 rooms and you want to allow 10 rooms of type 1

20 room avalable type 2, 15 rooms avalable type 3 – to book online

This may change from day to day if necessary.
