The Model Should look like:
Super2 = {
hotel: {
Best Western: {name: "Best Western of SF"}
Econolodge: {name: "Econolodge of SF"}
}
}

Subject: Re: CRUD test
There seem to be data consistency bugs in the test. Are "name" and "hotel"
being used in a pair-wise way?
Specifically, the first test is using creating one and checking for the other.
