    Hydra Balance was installed in our Crown Plaza Athens after a successful installation in the Holiday Inn Attica in Athens. It brought significant savings to both 5-star hotels and the real-time website interface provides very useful data, far superior to any competing systems. At the Crown Plaza, we saved 61%, amounting to €262,000 since installation.
