Dizma, as far as to whether there is "enough" sugar packets, it depends upon how much you use. For us, as two adult that don't sweeten their coffee but do use sugar on cereal and things, yes there was plenty. If you plan on making recipe that calls for a cup of sugar, you'll have to buy some.
gianna2006, for those individual replacement supplies you'll call housekeeping or the front desk. You can, however, purchase the Maxwell House coffee filter paks (8 or 10 per box) and a slightly larger box of soap at the resort store. Still expensive, but cheaper than the individual paks. They also have "Mickey" coffee in the resort store, and I think they work out cheaper than the individual paks, as well.
