Green Guest Program

Castle Marne’s Green Guest Program is a new piece of our Green Initiative. Guests wishing to help reduce, reuse, and restore will benefit from participation in the program and help us in our conservation efforts.


Reusable water bottles

Green Guests receive $15 off/room night or a free bike rental during stay.

All green guests receive a Castle Marne refillable water bottles at check in.

Guests agree to the following:

To set AC/heat to low and turn lights off when you leave the room.

To rehang any used towels that do not need to be laundered to let the Castle Marne housekeepers know that you want to participate in our towel reuse program. We will happily launder any towels or linens you require.

To bring any recyclable or compostable items to the kitchen, and we will dispose of them properly.

To use the new refillable Castle Marne water bottle provided at check in, rather than the complimentary bottled water which will cut down on waste and need to recycle.

Other useful tips:
Open blinds during cooler months to let the sun naturally heat the room, and close blinds during warmer months to help keep the room cool.

Rent a Castle Marne Bicycle for just $15/day or use public transportation to save gas and get some exercise while visiting Denver. Green guests can get one free bike rental if opting out of the $15/off room per night.
