Babysitter Needed for my Children

We are looking for a babysitter for our 3 1/2-year-old daughter on June 29 while we are staying at a hotel close to California Adventures The hours would be approximately 7:00 p.m. to midnight each evening. Our daughter will already be bathed, in pajamas, and ready for bed. We are simply hoping to enjoy some evening time in the parks with our older son while she sleeps. Responsibilities would mainly include staying in the hotel room while she sleeps and being available if she wakes up.
