We've thought about San Francisco. We went there once together when I was 8 months pregnant and LOVED it. We loved driving north and exploring along the coast.
Puerto Rico is a place we hadn't thought of. We've never been anywhere at all tropical. I think if we could find a place that was tropical but not too cheesy/commercial, that would be something to consider.
We also hadn't considered the southwest. That's an area we have no experience with at all. Someplace totally new could be fun!
What would Vancouver be like in April? I'm guessing rainy and cold, but I could be way off.
I've also heard a lot of great things about Savannah and Asheville. So many choices!
I am a teacher and I have a week off in the middle of April. That's when we'd be going. DD will be almost 5 (wow!) and is a pretty easy, adventurous kid. She does like her routine, but she can be flexible when there are new and interesting things happening. We'd love to go to Europe, but if we can pay for something entirely with miles, that would be better. Europe would still be quite a lot out of pocket. I'd consider some sort of small, remote eco-resort somewhere if we could be totally independent. Does that exist?
