Doesn't appear as though they are offering much for an additional $200.
It's risky to pay additional money thinking you will be part of a larger group with no guarantee. Only a few other gay people may book and you may find yourself disapponted. I once ran into a small group (6) of gay guys on a straight cruise that had been mislead by a travel agent into thinking there would be 400. Not that I'm advocating the "all gay" cruises either.
