dallas 4-some planning advice?

An old mate and I are getting together and having fun about the town and were thinking it might be time in our middle age to try an old fantasy, a 4-some with 2 ladies. I will be in a good hotel and it would ideally take place there. We'd like a diversity in the women, eg one white one asian or some such thing esp in terms of body types. If anyone knows how to set this thing up or has recommendations (or wants to recommend themselves and a friend) please reply to this thread or PM me depending on the content of your reply and whether you wish it to be private. Thank you all very much in advance - this would be in 2 weeks.
