You can google how to make your own paper coffee pods if you want to figure out how to brew your own coffee in the resort rooms. You just need some coffee, coffee filters and the bottom of a correctly sized drinking glass (to use to shape the filter and tamp down the coffee). It can get messy and I don't think its worth it.
The problem with the in-room coffee at Disney are the machines and not the paper pods. The paper pod format was invented primarily for single serve coffee machines that pump water through the pods under pressure (low pressure between 1 and 5 bars). While still popular in Europe, many of those machines are gone from the consumer/home market in North America (thanks to Keurig for killing them off). What remains are paper pod brewers designed like a regular drip machine. So, rather than pump water under pressure through a pod (which costs a lot of money to make), many cheaper machines (under $25) simply drip the water over the pod. The result of dripping the water over is very poor coffee extraction and weak and thin tasting coffee. The Cuisinart machines at Disney are designed for the hospitality industry and simply drip the water.
On my last trip to Disney (in November) I brought home about a half dozen Joffrey coffee pods left over in my room to brew in my pod brewer (which uses pressure). I have to say that it makes a pretty good cup of coffee when properly brewed.
