I used to get an Entertainment book every year in order to get decent hotel rates but I haven't done this for 5+ years now. My impression is that pretty much any room rate I could get through Entertainment, I could get some other way. Am I right?
Note that I rarely, if ever, used the book for restaurant discounts, just hotels.
P.S. The few times I did try to use a coupon and felt the merchant refused it improperly, I contacted the Entertainment company -- and got absolutely no help or support at all.
