You do not get EMH's with the AP unless you are staying on the property.
You get some discounts at places though many have been taken away.
The biggest thing to me is, depending on how much you go, you REALLY do save.
The biggest savings right now is free parking. You get free parking which is $9.00 per day. I've already saved about $200.00 in parking this year alone, which is INCREDBILE! it's worth getting an AP just for that if you go alot.
