Are they trying to rip me off?

Hi all. I'm going to be first time traveler very soon. My family and I are trying to make it to the Northwest. I have applied to different companies, and I've been trying to research. I'm not the sharpest tool in the shed so it is taking me some time to figure all of this out. Since I will be traveling with my family, we are going to need a 3 bedroom rental. The best rate that I've gotten with my rental and family insurance paid is 30/hr. Does this sound fair? I keep reading all these posts where some nurses are making into the high 30's and even 40's. Just wanted to get some information from seasoned travelers. Thanks.
