Socrates you aren't very good with those codes. Travel agent code is TVL, Marriott associate or family of marriott code is MMP. If you get by with an MMP code then please let me know how you did it folks...

Recap Code:

TVL=Travel Agt/Airline emp.
GVT=Gov't/Military
MMP=Marriott Empl. and family

These are the best discounts if you qualify. They will ask for verification too!

Good luck.
