Jamie, I can see that you are new and this website can be daunting at best. Please take time to read as much of the FAQ as possible as you will learn a great deal. I have several thoughts about your listing that I will share and hope you find helpful.
I am in La Quinta and also price for the several times the events and/concerts increase demand.
I reviewed your calendar and it seems to block out some dates needed for Coachella and Stage Coach.
Don't forget other events such as the March Tennis Tournament.
For an entire house I think both your cleaning fee and definitely your security deposit are too low.
Also, given the interest and planning for the big concerts, a moderate cancellation policy may not be a good idea.
I don't hold out much hope for changing your current guest booking unless you can show Air BNB that there was a system glitch at the time of the booking resulting in an incorrect price.
We are starting a La Quinta Home Sharing Club and you can join if you like. Linda
