I find that if I go for 3 days, I take my time to go to each and every park. I usually spend the majority of the day at each Park for the first 2 day.....even taking a break to go back to the Hotel to do some swimming ( if it's during the Warm months ) and/or do some shopping in Downtown Disney and/or the stores inside the Park ( which we usually don't have time to do ). On the 3rd day, we split the entire day between DL and DCA to go on all the rides that the kids like ( as opposed to going to the entire park ).
Either way....going for 3 days allows you to not rush while enjoying your time in the Park. This is especially important when you ( just like me ) have kids to deal with.
