I wish we had!
We had some fun moments at Six Flags, but it wasn't as fun as we expected. My oldest daughter is 6 1/2...too big for the kiddie rides, but not really adventurous enough for the bigger rides.
It didn't help that our day started out a bit negative...my husband forgot he had his pocket knife so he ran back to the car to put it away. He came back though the security line and empties his pockets on the way through. He went to pick up his Chapstick and the woman started yelling at him that he couldn't have it because it was a LIQUID!!! Now we are very much follow the rules people...so it didn't help that the people in front of him went in with bottles of water and a pop from McDonald's! There are signs that say no liquids with the exception of baby items (milk, formula, etc.), so he didn't understand why people walked in with huge amounts of liquids...but they were giving him a hard time about his lip balm!
There were signs everywhere that said it was the cleanest park in the world...I'm assuming WDW wasn't on the list to vote for because there is NO WAY it is cleaner than Disney! And they load and unload the rides SO slowly! It was CRAZY!
They say they have a family atmosphere, however, the shows had a lot of adult humor. Nothing terribly crude, and it all went over my kids head...but it still shocked me a bit. I was most shocked though by how people were dressed! Girls were walking around with their shorts unbuttoned and unzipped! I saw this more than a few times! There were SO many shirts with inappropriate sayings as well...one that stuck in my mind a high school age boy... "My better half (with an arrow pointing down)" My 6 year old can of course read and was asking what that means.

Ugh... I don't really think of myself as prudish or anything I just think there are certain things that aren't appropriate in a "family setting"
I know it isn't Disney World, and it isn't fair to compare the two...but it just reaffirmed to me how much I love WDW! Ha!
