need info on early morning short distance transportation

My wife and I are taking a Noe's tour on March 13th and need to be at the Farmacia Guadalajara at 7:30 AM.
The trip is five days so we cannot leave our car and will need transportation. Since we need to leave the house at 7:15AM we are concerned about reliable transportation and are not sure we can trust a cab. Are our fears unfounded about a cab ? Also, can anyone recommend any other person who is realiable that we can hire ?

Thanks much!

I never have a problem at that time of the morning. Early is 4 or 5 7am is a piece of case. Call a cab at 6am or the night before and make arrangements.

Where do you live twelveoaks? I know several people going, including my wife and my mom, perhaps someone can pick you up on the way?
