"Some have referred to Skagway as being a tourist trap overrun by folks from the cruise ships and that may be true to some extent but there is so much more to Skagway for the RVers that it would be a shame to miss it."
Much of the same could be said for almost any town in AK (or I suspect Canada).
Having recently visited Ketchikan, Juneau, Sitka (all for a day passing through) within the past 2 years, they're all more crowded than they were 40 years ago (when I first visited them)....but the scenery is still there, the attractions (historic or otherwise) are likely still there, and (almost exclusively) the crowds largely disappear with a short drive or long walk out of town.
