Beautiful Lakes To Go To For A Vacation?

I want to start a tradition of going every summer with our family to a beautiful lake. I am looking for opinions of destinations with beautiful lakes for families. Although I love looking at beautiful outdoor scenery I am not much of an outdoorsy girl ;) and I have 4 daughters who would rather be inside as well. So I would prefer maybe hotels near by instead of only campgrounds. I have looked at Bear Lake in Utah and it looked really pretty. So just give me some suggestions. Thanks :D
