OK, I need some WWDD (What Would Dee DO?) Advice!
We are taking a trip on the darkside. So far, we are doing 3 days UO/IOA and 1 day at Kennedy Space Ctr. That leaves 1 day for either Seaworld or Magic Kingdom. My kids are not big coaster fans and, I know it is not the same, but we at Mystic/NE Aquariums all the time. DS wants Seaworld and the rest of us lean towards MK. I am worried that 1 day at WDW might just be a tease.
SO my travel guru- WWDD?
Woah! I was surprised (and pleased) to see this report pulled up again! Of course, now that I finally finished my class trip report from June, I need to come back here to finish the Atlantis trip.
We did both on our darkside trip- 1 day at MK and 2 half days (essentially 1 day) at Sea World- the SW tickets were buy one day, get a second free.
I was going to say that the tickets for SW are probably cheaper, but I bet not significantly so. That's one factor. One day tickets at Disney s*ck! So expensive! But what I did when we decided we were going to go to MK is to start charging up my Disney Visa, and we used that to help pay for the MK admission.
It had been 7 years since we had taken the kids to Sea World, and now I don't know that we will be rushing back. My older son really loved the thrill coasters- Manta and Kraaken, but you said your kids are not into that. My younger son doesn't do the thrill rides, so we did a lot of shows. The older one didn't love that.
We all love sea critters, but I have to say, there is so much more to do at MK.
The day we spent there after surprising our boys was probably my favorite ever at Disney. I loved everything about it. Getting there early, pulling a gazillion FP (which doesn't work as well now

), lunch at Columbia Harbor House, more fun in the park, and then taking a break to ride the monorail and eat at Kona. Then back to the park.
I have the chapters of this trip report linked in the second post, so if you want you can take a peek at the SW and MK chapters.
Where are you staying for this trip?
Oh, and if you really want to know WWDD... For your aquarium and amazing water park fix, save your pennies and go to Atlantis!!!
