I was able to put together a spur-of-the-moment weekend trip for late June. Arrive late afternoon on a Friday, depart early evening on Monday. Played around with National and Mary's and this board codes and all, came up with a $72 rate, all taxes and fees incl for the 3 days, full size, Emerald Reserve. I used the AMEX contract ID, a free weekend day from Entertainment Book and a product ID of B39401. I forget where that product ID came from, but it was there I think from a National web offer or something. Anyway, just wanted to pass on some good results. I really like the new (for me at least) View/Modify section. I whittled my rate down from over a hundred dollars to start with by modifying a number of times. Each time a better one I did the 'continue' and it was nice to see the old and new side by side to make sure there were no errors. Thanks again to everyone here.
