I'm still not quite sure about how to include information for gays and lesbians into the article -- on the one hand, we don't want to stray from the templates, which don't provide for a section on gay and lesbian information. So it seems prudent to include it under the other headings like "See", "Drink" etc.
On the other hand, you probably do want to mark certain places clearly as "gay" or "lesbian", for two reasons:
gays will be especially interested in those. Many gays feel more at home in gay locations when going out, and like to check out the local scene when traveling to another city. (Cologne has about a million gays from all over Germany and the neighbouring countries visiting for Christhopher Street Day.)
most straight people will want to be warned before stumbling into a gay or lesbian location -- they don't want to go to a place because it was recommended in Wikitravel, only to sit there uncomfortably and ask each other, "Hey, do you know why there's only women in here?" Yes, in most cases it's perfectly acceptable for straight travellers to go to gay places (except if a woman wants to go to a fetish bar with darkroom ... d'oh!), but most will want to be forewarned.
So I guess there's three options:
include the info in subsections under "See", "Drink" etc. Doesn't break the template, makes it hard to hunt for information, you have to skip large pieces if you're not interested
use a special section "Gay" to group the information, with the usual subheadings ("See", "Drink", etc.), which makes it easy to find, easy to skip, but breaks the template.
Create a sub-article, for example Cologne/Gay. I don't see sub-articles used much in Wikitravel and don't know the policy.
If this is a general issue, this is perhaps better discussed under Gay and lesbian travel or in this style guide.
