I love St. Augustine. We went one year and really enjoyed ourselves. I want to go back, but the husband has so much less vacation time than I do.
We usually do something similar. The husband, dogs, and myself have gone to Lake Travis (near Austin, TX) and spent the week for the past several years. No phones, no cable, no internet (and thus, no work)...it's usually the highlight of my year. We're too far away this year, but are thinking of maybe going somewhere (warmish) in Arizona.
