Thanks for the respose and input. I did not feel that I had double booked since I had not confirmed with either one, merely was checking availability more than a week in advance. In the past I've been burned because I put all my eggs in one basket and then ran out of time to make other arrangements when the first one didn't pan out.  In fact this time around I sent  emails to five ladies and only got two responses. I will make sure and communicate with the second lady so there's no confusion. Thanks again.
