Well, we're a little different from the others who have posted. We only go once a year now that we own DVC, but before DVC we only went every 3 years, so for us we are going much more frequently.
We would probably go more frequently, but I teach and have a 12 month contract. I have specific weeks off during the year and ALL of them are during prime season. No way I am going to get DH to WDW during Christmas or Easter (well I got him there during Easter once and that's how I know he'll never go then again). The busiest time I can get him there is Jersey Week, but that's a walk in the park compared to the other weeks of the year I have off.
