I sympathize with your situation and would try to do the same if I ever got stuck with one of those silly "resort fees," but as a practical matter most hotels above the low end charge more than $18/day for Internet access alone. You could find that they'll take the $18 off, then charge $20 or $25/day for the part you do want. It might make more sense to think of it as an "Internet access bundle" by a funny name that happens to include a few things you don't need.
