Glad you figured it out. From my Ipad I always have to go a round about way to get to the booking tab. On the right side of the page click "how to book" then click the big "Check Now" button also on the right side of the page. Another note for ipad/iphone bookings is you have to scroll down through the entire terms and conditions before the booking button will become enabled. This tripped me up a few times too.
