Seems like a suit would dry in the sun in less than 20 minutes, if you flip it over at 10 minutes or so. Most of the times I have been to DL, the humidity is not enough of an issue to prevent anything from drying in an hour or two, when hung. YMMV
I normally hang my suit in the bathroom and it's dry in the morning. I assume they have coin operated driers guests can use for personal laundry. I know the suites in DVC section of GCH have driers in the unit. They were slow, stacking W&D and I assume electric (not gas).
