I'm a west coaster, so going to DLR is only a few day trip at most, so going to see other parks or features is natural. WDW, is an expansive trip. You can spend 3 days in just one park and barely see everything. You could do 2 weeks at WDW, and still come away, thinking you never saw everything. So with that said, you can be a House of Mouse man, but you still try to get to see other places.
