Babysitter Needed For 11 Yr Old's Birthday Sleepover Party In Cambridge

I'm looking for a great babysitter to supervise a sleepover birthday party for our approximately 14 10-11-year-olds. The party is taking place in a three-room hotel suite, and you would have the separate king room to yourself. I, mom, supervised them myself last year in this same scenario, but this year I am sick and won't be able to. They were VERY well-behaved last year. You will supervise pizza eating, birthday cake lighting, two trips to the pool (one at night at one in the morning), and helping with whatever comes up. Someone from my family will be on hand nearby just in case. Obviously, tip will be generous.
