Seth references Mark Polino as to why don't hotels allow you to use your room key for vending machines at the hotel.
I was recently at The Wilderness Resort in Wisconsin Dells and their restaurants in the resort allow you to use your room key to charge to your room. Why not extend it to vending machines? For resort towns, why not take it further? Why not have an agreement with nearby grocery stores for long-term guests to be able to use their card for groceries?
This, to me is TRUE value-added. Existing to make the customer's life better/easier/more fulfilling.
Who will start this to start the next "industry-standard" revolution in the hospitality industry?
