Hello Olly.
I understand I am using WPPizza in a fashion that is not typical so this request would not be needed by the majority.

You may remember that we are a small hotel. Guests order room service online select their room number (via a drop down on the checkout form) and orders are delivered.

We have one elite “smart” room that has a dedicated iPad for ordering. This room has an alternate menu, but of course links to the central orders page for checkout. It being a “smart” room with a dedicated iPad, it seems “dumb” that they need to populate the room number at checkout. Can you think of a way (OTHER than customize programming) to have it auto populate the room number when it being generated by the iPad? Setting up a sub domain and an entirely new instance of WP/WPP is the most linear way I can think of (that is within my skill set)

Thanks
