My parents recently bought a lakehouse in NW AR at Beaver Lake. My two brothers live and work in Fayetteville, which is about 30 minutes from the lake. It is a beautiful lake and the girls had a great time on the boat. If you are looking for quiet and peaceful escape -- this is your place. Rogers is a quaint town -- check out Slim Chicken's restaurant there. It has great food (and happens to be one of my brother's restaurants, so I am really not biased at all).
I will try to add some more pics soon -- it is really gorgeous there -- and my parents have a great view of the lake.
