When my wife and I visited Tokyo DisneySea, we enjoyed the attractions but found the overall EXPERIENCE of the park is what sucked us in. On our second day, in fact, we rode very few attractions but just wandered the park and enjoyed layer upon layer of immersive, themed detail. The way the OP explained the Phantasialand experience, it sounds like even a non-coaster person could have a wonderful time exploring and experiencing the environments, no?
