I voted for POR, and have stayed at all mods except CSR (which doesn't really appeal to me since my other vacations have been in Mexico).
I love POR for its theming (it is the exact opposite from where I live), the ambience, that feeling I get when I step out of the Steamboat Company, and I am transported to another world. There's no hustle and bustle; rather, it is relaxing and charming.
I love POR because along with POFQ, it offers boat service to DTD.
I love POR because of Piano Man Bob.
I love POR for the five quiet pools, hot tub, horse drawn carriage rides, the fishing hole, bikes, marina, landscaping and early morning/late night walks.
My DS(6) loves POR for trundle beds (he feels like he's campig out), Ol'Man Island, cane pole fishing, and the River Adventure Cruise.
And, while I normally stay in the AB section, sometimes will stay in the mansion section and it will feel like a whole different vacation!
