Here's my 2 cents worth.
Take a look at the image I posted in this thread.
For Sis, by request
I took it with my D300 and the 18-200 VR. It's plenty sharp as you can see. This lens almost never comes off my camera. I have an 80-200 which is so sharp it will cut you, but for everyday purposes the 18-200 delivers beyond my expectations.
Best wishes and have fun at Disney. My family spent a week there back in March and had a great time.
