The venues described in the series aren't entirely revolutionary. There are numerous venues which already fit in to the urban nudist oasis category. N magazine 31.4 talks about Fawlty Towers in Cocoa Beach, which is a hotel that recently turned nudist. Another recent addition is Clover Spa in Britain, which is more like a bed and breakfast. A commenter pointed out his "Clothing Optional Home Network" of bed and breakfast venues. (There are many more, including some traditional nudist venues which happen to be at the city's edge.)
The existing venues basically market themselves as hotels. You go there, pay a substantial sum of money, and enjoy a room for the night. Some go a step beyond and allow guests to enjoy the facilities for a day fee. This is often a substantial sum of money and they feel like they need to stay all day to make it worthwhile. With these policies, the venue attracts vacationers and people who have the day off from work. It becomes a tourist destination and a hotel. Although this can be profitable, my venue would focus on a different market.
My policy for an urban nudist venue would be to also take the next logical step: charge by the hour. With this policy, the venue would provide dual roles. It can still be a tourist destination and hotel, but it will also become an entertainment establishment. It would compete with things like bowling alleys, skating rinks, gyms (both workout facilities and classes such as yoga), theaters, arcades, restaurants, and bars -- all of which you pay a small amount of money and have some small duration of entertainment or use.
Think about how much time you spend at vacation destinations. Perhaps a week or two each year? Now think about how much time you spend at the entertainment establishments I listed above. Likely a few evenings each week and most weekends the rest of the year. When people want to get out of the house for a while, or have time to kill in town, they can stop in.
If anyone is curious, a small fee and an hour of time is all it takes to give nudism a try. (An hour is usually all it takes to become hooked, too.) As people drive by the venue, many will be curious. They'll think about it and talk about it even if they never go. And this would be good for nudism.
How many nudists do you know on TV? Probably none. Is nudism a talking point in each political election? The obvious answer is "no". However, gay rights are a talking point and I'm sure you know several gay characters on TV. Here are the stats: 8.2% of Americans have engaged in some form of same-sex sexual activity, yet most Americans think 25% of the population is gay. Per the NEF poll, 25% of Americans have gone skinny-dipping or nude sunbathing in mixed company, yet many Americans think we're a fringe group. Why are these statistics inversed?
I believe that the difference in attitudes is related to the difference in primary social frameworks over the last 50 years. Nudist resorts are hidden away in rural areas, keep to themselves, and in general become forgotten. Gay bars, on the other hand, are in the middle of town. They are seen on a daily basis. They are talked about among the community. They are frequented by a lot of casual visitors, both regulars and the curious. They are a social hub for tight-knit local communities who are actively pushing for change.
I'm not advocating that we open a bunch of "nudist bars" to mimic the success of the gay culture. (Legally speaking, establishments serving alcohol and offering nudity are heavily regulated, so a "nudist bar" would be very difficult to open and operate anyway.) But if similar facilities -- minus the alcohol and plus the numerous features I've mentioned in this series -- popped up around the country, I believe it would have a huge positive impact on nudism long-term.
In conclusion, my revised prediction for the future of nudism is within an urban setting. Existing urban venues can be repurposed with casual nudists in mind, in cities which are already ripe with demand. A healthy mix of people will give it a try. Naturally, a strong sense of community will develop. With the increased visual presence, nudism will become a topic of political debate and mainstream media. Change is coming in the next couple decades, and I'm already looking forward to it!
