I haven't induldged in a while and my 411 preferred has expired - can't renew it in time via CC.  I do have one recent enough ( and fairly regular) date who will give me a good reference, plus some older ones too, never had a problem.   I am traveling to Vegas next week and have found several ladies who I would like to see. They all have pretty good screening processes.  Seeing it's Vegas and a Major convention I submitted requests to all three, since they all require screening before booking though, I put down  the date I would like. My question is, if more than one accepts me, how do I decline? I will accept the first one that accepts me so I won't be stringing any of them along, just trying to cover my bases. What is the proper way to say, thanks but no thanks?
