I'm not a hoterlier but we implement a lot of these for our events and looking for these things are things we take into consideration when choosing a venue.
We like to reduce water bottles so we look for hotels with water filling stations. This year for staffing our events rather than fly everyone around, we found the bulk of our event staff support from a local DMC. We reduce the number of printed items on site, opting for a mobile app to keep things green.
