I am in belief a double oven comes in handy, especially during those time when you have lots of family & friends over ; you can keep things warm after preparation its great to have food hot that's suppose to be hot. In the summer you can prep and just toss it in the oven while you are decorating or getting ready. I say go for it!

If you want a double oven go for it but I had one in the corner of a vacation home and always thought the corner placement used up too much space in a small kitchen.

For a summer home a corner double oven might not be needed.
