I've done the second for a few years when I lived in the US - Indiana, to be exact, which is quite humid. I couldn't really afford the driers at the laudromat, so I brought stuff home to dry inside. No issues, summer or winter. Drying time here (Norway) in winter is about the same as high humidity was in the US. Summer is the dry season here - there is often a forest fire watch and a ban on open flames/fires. In general, as long as there is air flow, you are fine. It'll take longer/shorter depending on humidity and air temperature.
