I've stayed in both. Since it is just you and your wife, you might like the villas better. In the Studio, you will have the queen bed plus a couch that pulls out in to a full bed as well as a microwave and a little area with a sink.
The villa building also has some quiet sitting rooms you can use.
In the regular rooms, you will most likely have 2 queen beds and a couch/daybed. There will not be a sink or a microwave.
My only complaint about the villas is that they are closer to the road and we did have more road noise there than when we stayed in a garden view room in the main building.
