But otherwise, that's the only page, the "Book My Hotel" button is at the bottom.
That is very good to know.
On UK site I can modify the "main contact" traveler name and then it offers a separate section for Passenger Information for hotel arrangements and again I can input whoever I wish to. As I mentioned up-thread, the only field that is grayed out is the payment info/cc. But as long as its not a prepaid reservation you can pay with another Amex at the hotel at checkout.
