From my perspective the idea of a database of locations, including hotels would certainly be very advantageous. Indeed if anyone reading this would like me to place a recipricol link on my website I would be delighted to hear from you and hopefully we can help each other get business.
For me, most of my subjects (and myself) feel more comfortable going to a neutral venue, and the problem is finding locations which are reasonably priced and 'open minded'.
I checked out hotelbdsm, and it certainly is a grand location, perhaps too grand for some of my clients, but ideal for group hypnosis fetish events.
Do contact me if you are aware or are able to offer a venue, or indeed if you have any queries as to what I offer or what I am looking for.
