Just print out a form and sent it in via fax with your bar preferences. Or even just add a page to the one you send in with any requests and put your name and booking number on the second page.

The "online" forms have not been working that well. I dont use them at all right now. Still some little problems with that so you may be better off sending it in by fax anyway.First time guests get the same benefits as past guests (except for the society discount and past passenger party)

This is NO guarantee the bar will be set up though. It happens about 50% of the time the best I can tell. The stewardess will get it for you very quickly on boarding though so it is not really a problem.
