Los Angeles. Definitely. Penn would love it, your parents would love it, and since I'm hearing mini-Belmont is give Ami siblings, I'm sure she'd love it too. ;) I'm actually loving that, by the way. It totally weirds your brother out, so it's really kinda hilarious to think about.
Seriously, though, if you and the kiddo and the dog need a place to stay, you're always welcome to crash at my place there. You'll just have to share with me and my mini-me from time to time when we come to visit. It's an option, at any rate!
