Drupal 7 existing Booking Page, redirect to booking-confirm on confirmation and booking-error for error handling

I have current booking page in Drupal 7. it's fully functional and working but I have a small task. Current booking page handles [login to view URL] error handling, normal booking flow and confirmation on same page. I would like to split into two more redirect booking-confirm and booking-error url. This is simple task using form[redirect] and might have to create new custom module that can handles redirects. Any help would be appreciated.
