I was concerned about the same thing. We purchased the Iris and I'm not keen on where the dining room is. So, I decided to use the dining room area as an extension of the living room, which it is anyway. The dinette area is large enough to put a formal dining set in, I had it measured and I believe it will look lovely next to the patio and window. We want a more casual lifestyle.
In our current home we have a huge living room which we use all the time, I like the openness of the Iris/Lilly.
It's wonderful having the opportunity to have choices. We are so excited about this new chapter in our lives and I know you are too.
I know you will make the right decision.
