We have been to WDW about 15 times over the years while our familly was growing up. We have been three times without kids and enjoyed every time. The last three times I have used
www.tourguidemike.com.
It was the best $22.00 I ever spent. You have to do a lot of research yourself but the amount of information provided is amazing. He will also provide a sample tour for the number of days you need.
Look at the website and if you have questions about it or any of the parks I will answer what I can.
I guess we are still kids at heart as we absolutely love Walt Disney World.
