Ugh - I need a vacation.

Just as the wife and I were getting over the lingering colds we caught a few weeks ago at the jr high winter retreat, she gets nailed with a bad case of bronchitis that could have tipped into pneumonia (thanks to her asthma) and I get a real bad head cold. Since she works with babies, she has had to take the whole week off from work and I ended up staying home sick for a couple of days. And I came to the somewhat obvious conclusion that we need a vacation. We've only taken a few days off since we've been here - almost a year now - and most of those have been spent with family. I think I may be starting to burn out a little bit. Anyone have any cheap but fun & relaxing vacation ideas?
