I guess if you are used to Florida, the thought of California is scary and vice versa. Kind of the same reason I am afraid of trying another cruiseline other than the one that I always choose. You just get comfortable with the one you are loyal to, and it's a lot of work to get to know something new, and work isn't something you really look forward to on a "vacation". When I was younger and didn't have kids, nothing scared me at all. I mean, I have visited some pretty intimidating places, but having a young family in tow changes everything. I think that if you are used to WDW and how spread out everything is, DLR might be an interesting, more convenient change, especially seeing how easy park hopping is. Literally just across from each other. I couldn't imagine just getting the "one park, one day" tickets because I like bouncing back and forth, especially since my 4 year old has favorite rides in each park and insists that he wants to ride them "NOW!". Hopefully as he gets older he will get sick of the Submarine ride, because I am so sick of that one!
