A lot of that will depend on when you go and how long you stay. Tropicana has a deal where they take $20 off a night when you stay 5 nights or more. It brought the room down to right around $100 a night before taxes and fees when we were there at the end of August. They don't have free breakfast, but they do have a refrigerator and a microwave so we just did our own continental breakfast in the room (cold cereal, fruit, oatmeal, muffins, etc). They do have a parking fee, but they don't have a resort fee. Best part, it's right across the street from the crosswalk and there are a couple of affordable eating options right there.
We actually had a room booked at the Desert Inn and Suites and moved over to the Tropicana because it saved us about $200. My brother stayed at the Desert Inn and Suites that same week we were there (he had a larger party than we did) and wasn't impressed by their breakfast or pool situation so I was glad we switched.
