Babysitter - Full-time / Part-time

Hi, my family is traveling to Branson next week and we need someone to stay at the hotel with them Tuesday morning while my husband and I attend a meeting. The hotel has an indoor pool, so the ideal applicant would be comfortable taking them swimming while my husband and I are gone for a couple of hours. Kids are 10, 6, 4, and 2. The oldest two are good in water; the youngest two are not yet, but are very cautious and will not venture far off the pool steps without a grownup.
