We usually take about 4 vacation trips a year and make sure that at least one of them is a new destination. The other trips (usually Europe since we've seen most of the U.S. and most of Mexico now) are filled with alot of fun and alot of activity because we love to see/do new things, meet new people, etc. But we still make our annual treks to Aruba to just "do nothing", relax, and re-charge the batteries.
If we could only take one vacation a year though (hope that never happens! ), we would probably only visit Aruba every couple of years. As much as I love it, there is too much of the world to see and experience. I went ziplining on a canopy tour just this past weekend in Northern MN near Lake Superior - I STILL have a smile on my face from that experience and being able to see the land (lakes, 300 yr old trees, etc.) from that high up as I flew through the air.
But still looking forward to Aruba in Sept....to do a little bit of nothing.
