Good start but the real issue is many properties play games with availability and difficult to find awards search 1 night at a time. Your tool would not work for someone who wants Alila Ventana as their standard room requires 2-3 night min, Andaz Maui we all know, CVR on holidays and weekends also require a 2-3-4 night min, recently I booked a 15 night block at the PH Aviara to get the 5 nights I really wanted to show up. I'm sure the list goes on much further.
