So, not actually a sabbatical, in so far as your job will not be waiting for you when you get back? Just checking. My husband also uses the term "sabbatical," just because he doesn't want to have a conversation about his age or how he can afford to do it.
There are a number of threads, many using the phrase "mini retirement."
I have personally watched too many people leave in good times, then be job hunting during a recession. That is fine if you have several years expenses saved up, a bit more troublesome if the plan is to spend what you have then go back to work.
