I would like to set up a very simple online travel agency just to book hotels. The content and everything else would come via XML from a 3rd party provider and the overall site layout and design should be similar to kayak (sleek and not overloaded). The only prerequisites I have are:
.) There should be a voucher field during the checkout process where the guy can enter a voucher/promo code displayed at the homepage, which then gets deducted (should only work for preset parameters like specific hotels, dates, rooms, etc., which I wanna be able to actively set myself to promote certain hotels etc.).
.) A way of selectively modifying parameters on the booking site.
.) Different currencies
Regarding the last point, I know that I get most of the informations via XML from a 3rd party provider, but I would like to be able to selectively modify certain parameters for promotion purposes.
