I checked "every single day", but it needs some explanation.
We usually go into a park every day, even if it's only for a couple of hours. Latly, what we have been doing(if DH and I are travelling alone) is go into the park in the AM, go to the pool in the afternoon, and back out, either to a park, PI, the BW, or shopping at night.
So while we do go to a park every day, we do not "commando tour" any more.
If we are with others, we tend to spend more time in the parks, especially if they are folks who don't get to WDW as often as we do.
