Your code works, but you need to execute it after tool bar is active.

If you add your code to your .emacs like this, your problem should be gone:

(add-hook 'after-init-hook
          (lambda ()
            (define-key global-map [tool-bar omar-button]
              '(menu-item "Hotel" omar-hotel
                          :image (image :type xpm :file "/usr/share/emacs/24.3/etc/images/jump-to.xpm")
                          ))))
