We've been married for 16 years, and have gone on one big anniversary trip, to San Francisco. That was in 2007. We've also gone to the beach for a weekend alone once. Other than those trips, we have never been able to really afford to go away alone AND take a family vacation. Having to choose, we've always chosen a family vacation.
We do always go out for dinner though, and we ship our kids to my mom's house overnight. So, we do get alone time, just the two of us, but it's at home. It's actually fun...we watch movies, eat breakfast in bed, etc.
ETA: I forgot that we went to WDW for our first anniversary! My SIL and BIL gave us their DVC points to use!!
