I agree about having a place to sit. Even if a store is too small to take up room for a kid's corner or spot, having a place to sit would be really nice. (My kids sit outside on the curb - by their choice - when I go to the LQS because there is no place to sit inside.)
I also like having one or two nights a week with later hours to accomodate work schedules. One of my LQS has one night that it is open until 8PM. I also cannot sign up for weekday daytime classes, so having classes in the evening and on the weekends is great!
