HEI Online is an online booking website for exclusive members only, but as a  member you have access to these incredible rates free of charge! These rates are not open for the general public, meaning you have to sign up before you can start your hotel adventure. If you find cheaper rates (with the same conditions and within 24 hours) anywhere else, we have a “Best price guarantee” that means that we will happily refund the difference – this will guarantee you the best possible rates. With 100 000 hotels all over the world, you can travel anywhere you would like.
