DH, DD-7 and I are vacationing in DL in April. In-laws will be in Vegas at the same time (without children). DH, DD and I want to hook-up with them for one entire day in Vegas, but DH and I would also like to do some adult-only things (gambling, show, etc.) with the in-laws for a few hours. Are there any reputable group supervised children's play areas that DD can play at for a little while? Please, no flames. We are the 3 musketeers, but Dh and I would like to experience a few adult activities while we are in Vegas for one day. Thanks.
