Coronado Springs is a moderate, ASMu is a value. Larger rooms. More comfortable beds, IMO. (but that could be changed with renovations)
We also like the added amenities at moderates when the budget permits. Paying extra for specific preferred areas is nice at ASMu, but I would rather put that money towards a moderate stay. CSR rooms are comfortable and have an appealing design. CSR is definitely on the top of our revisit list as soon as the construction is finished!
FYI:
You have great pools, hot tub, a salon, fitness centre and beautiful grounds. We really enjoy the dining at CSR (but we are in the minority there). a new restaurant over the water sounds divine. Four bus stops mean that you aren't far from a bus stop wherever you are located.
We love CSR and, although we also really enjoy our ASMU stays, I would pick CSR.
Enjoy!
