Sitter Job in Indio, California

Hi ! My wife, our two kids and I, are planning to do a RV trip during our stay in California. As we will attend Coachella Music Festival, we found a place in Indio, where we might be able to settle from 8th April till 13th April.The place is a Resort and we would need a Nanny to take care of our two kids ( 3 years old an 1 and a half years old ) while we are out there. We will need the nanny from Thursday 9th till Monday 13th. The Coachella will start on Friday 10th but I would like to spend one day before with the nanny in order for our kids to get use to her. Regarding the working hours, I'd like to know if the nanny could stay till late at night because the last concerts will end up around midnight. As we won't be that far from the resort I think we might come back around 1 a.m. I really don't know what is your policy regarding working hours, and how we could organize things so we can feel secure in having someone taking care of our kids during such "specific " conditions. Looking forward to reading from you soon or you can also call me on those number : 33 7 83 ... My best regards, Christopher M.
