Baby sitter key west fl?

I am looking into eloping or having a small private ceremony in key west. My idea is that I will have my two 14 year olds, and a few friends join us. I want a simple wedding & maybe just go to the hotel poolside/beach afterwards for a tiny reception.. cut cake, dance& allow my kids to feel involved.. them im thinking of hitting the dance clubs with my friends and husband. Are there any hotels that offer baby sitting? One we go to often here in texas does and my kids love it.. if not what do you think would be a good alternative? Care.com? My kids dont need a sitter at home but Id like someone to keep an eye on them while they either swim or go play on the beach for a few hours.
