The coffee makers at the resorts are the 4-cup capacity ones. I think they are all Mr. Coffee.
They use the smaller 4-cup basket style filters.
Regarding the 1/2 and 1/2, I have never seen it sold at the resorts. Most food courts have the dispensers for the creamer.
Maybe this can help, places like Costco and Sam's club sell boxes of the individual creamers.
Sam's club has Land O Lakes 1/2 and 1/2. I buy this not only for travel but for work. I usually throw a bunch in a ziplock bag and store in the suitcase. They are convenient and best of all, they don't need refrigeration! They also, have flavored creamers there.
Good luck!!!
