Renting a car, staying off strip

We always rent a car when we are in Vegas initially because it allowed us to book a cheaper room off the strip. Las Vegas has always been one of the cheapest places to rent a car. Prices are up because of the daily LVCRF (Las Vegas car rental fee). In my opinion, most of the rooms that we have slept in are very similar with the exception of downtown. SEE MY ROOM PICKS RINNING DOWN THE RIGHT SIDE OF THIS PAGE. My guess is that visiting gamblers gamble more in the casino where they are staying. Casino's have to stay up to date on rooms to continue generating business. We have been known to sleep in three different hotels during our 6 day trip. We are actually staying in three this trip. Some might say I would hate that (my husband did initially) but the way I look at it is I spend very little time in my room, a daily shower and sleep and if casino A will give me 3 night and Casino B will give me 2 nights free, I'll take it. I take any free rooms, meals or casino play that I am offered. These are comps and Las Vegas is full of them but they aren't actually free, usually based on play ($$$ spent gambling) at their establishment.
