Besides these boards, try miceage.com and mouseplanet.com for info. on DL, as well as Disneyland.com.
As for comparing MK to DL, DL is 3/4ths the size of MK. The weather will be cooler and drier than Fla. We were in the park for 11-13 hours daily, something that we would never try at MK because of the heat. The rides are much closer together in DL, there are more of them and the walkways are narrower than those in MK.
When the park is crowded you will definitely know it. Get to the park before opening, if you have little ones hit Fantasyland first and use fastpesses whenever possible. Note, there are no fastpass rides in Fantasyland in DL.
These tips are the same for Fla. as I'm sure you know.
