Both hotels invite to engage guests employees and business partners and organising special events in the dark.

Earth Hour 2016 is the united call for environmental action around the world. Cities in 92 countries shut off their lights for one hour on March 19 to observe Earth Hour an annual event geared at showing support for taking action on climate change issues. Both hotels in-house guests have been given the option of participating by switching off the power in their rooms from 8.30 to 9.30pm. In the rest of the hotels only essential lighting will be kept on.

At the Park Inn Muscat hotel in house guests will be invited to spend that time at the Sama Terrazza rooftop and observe the event under the stars with complimentary refreshments provided by the hotel and diners at RBG Grill Muscat will have their meals by candlelight during that hour. At the Park Inn Hotel & Residence Duqm guests will be invited at the Ocean Restaurant open garden offering complimentary refreshments.
