I have the same concerns as Raven. Most people try to stay home as long as possible but if you're planning on walking you'd want to start out sooner rather than later.

I think it's certainly physically possible but might be a little stressful.

But you don't need to decide right now. If you'd like to keep it as an option, just work out a contingency ie. someone you can call to pick you up at a moment's notice.
