Accor celebrated the 90th Birthday of the Grand Mercure Melbourne, Flinders Lane building by recently completing a multi-million dollar makeover of the hotel.

Accor Vacation Club have spent $4 million to bring the property back to its glamorous glory, so well known by stars of stage and screen over the past two decades.

The building is constructed on land which first belonged to Dr. Jaeger’s Sanitary Woollen System Company — a long-winded name which would evolve into the well-known fashion brand Jaeger.

If you’ve ever wondered exactly what goes into running a hotel, Accor hotels chain is giving its customers the opportunity to find out.

A total of 41 hotels across Switzerland will be opening their doors for one day in October to allow visitors to find out exactly how things work behind the scenes.

Each hotel is compiling a specific program on October 10, ranging from bar workshops at the Novotel Bern to housekeeping demonstrations in the Ibis Locarno.
