Melia San Lucas is a beautiful resort, a little $$ though. Have you thought about Villa Del Palmer or Villa Del Arco? (VDA is new, so the rooms are nicer)
I know a guy how owns a timeshare in Villa Del Palmer, were staying there while were in cabo, we got a weeks stay (has to be booked for Friday or Saturday and stay a week) one bedroom, two bath for around 900.00. You also have the option to do AI for an added price. Let me know if you want his contact information and I can forward it to you. Christa stayed at VDP as well and said it was nice.
