DH's goal is to visit all of the Disney parks with the exception of maybe Hong Kong. So far we've been to WDW, DLR and DLP. Our home park(s), however, is WDW. We live 2 hours away and have held APs for at least 7 years. That said, we almost like DLR better (so I guess there goes the home park theory). I think for us, its more about specific attractions that we prefer at different parks. For instance, we actually like WDW's Space Mountain better, even DLR is newer, smoother and has a soundtrack. For us, the DLR version is just a big corkscrew with no excitement. That said, DH's favorite ride in any park is the Matterhorn. DLP has the best Thunder Mountain, IMO and Phantom Manor and Pirates there are must-dos. I also like DLP's castle the best. The dragon underneath is amazing! For our daughter though, DLR has many more dark rides in FL and she loves Monsters Inc at DCA. We also love Indiana Jones, which just isn't anywhere else.
