Link back to website when no longer booking.

When a user begins to direct book on my website, if they change their mind once they've started, there are no links to go back to my website. The only thing they can do is actually finish the booking, or use the back button on their browser (this works, but is not user friendly).

I would like there to be an obvious 'Return to CondoinPC.com' type link on the booking page.

Hope you agree! Thanks, Greg
