One-time sitter at our hotel for 2 sweet little girls - Full-time / Part-time

We are visiting Palm Desert for the week and looking for a sitter for one night so parents can have a date night. Our girls are 3.5 and 1.5 years old, very sweet and easy going personalities. They enjoy music (singing/dancing) and reading books. We only need sitter to serve and clean up dinner, do some play time/reading, and put our girls down for bed time. Our 1.5 year old is very easy to put to bed. Our 3.5 year old takes a little more time (a little more convincing :)) This will be in our hotel room at Marriott Desert Villas 2
