Also, be sure to pay attention to which program has properties convenient to destinations you plan to travel to. Not all programs have properties everywhere.

So, look into each program for Seattle and New England (and anywhere else you plan to go) and see what is available. Make sure they are properties you are willing to stay at. If they are really expensive (or really lousy looking) you might want to consider a different program that maybe has more options near your intended destinations.

Obviously there is a lot more availability in most programs domestically, but still worth looking into. This made a big difference for me when I was picking a program.
