I myself have never been to WDW i have only been to Disneyland. To me WDW in six days would never work. I have a couple of friends who have gone to Disneyworld for a week and they didnt get to do the things they wanted to bc the park is huge! Disneyland is always fun and you can get to everything in 6 days and with California adventures having new rides it should be fun. hope this kind of works.....
I would rather be at WDW. I have been to both, and I feel there is more area to cover and things to do in WDW than in Disneyland. I love both, but will always love Disney World more!
