Pros:
-Marriott points (for some)
-Usually lower cost than deluxe disney (outside of OKW, SS, perhaps AK) - and renting points.
-Deluxe benefits such as evening hour access.
-Location, if want to walk ~15 mins or boat to Epcot/HS
-Restaurants are pretty solid - and have crescent lake options
Cons:
-Theming - If you are used to any other deluxe or moderate Disney hotel, you will be disappointed with the lack of theming. If one of your favorite things about going to WDW is the 'Disney bubble', I wouldn't stay here.
-Parking fees - 38 bucks per night. If had a car for a long trip, I wouldn't stay here.
I've stayed here for a couple nights only on a split stay to get extra evening hours on the assigned days. It has it's benefits, but the lack of theming has it way down my list....but if you are used to staying off property, this is still a big upgrade.
