We used Rainbow Kids as we wanted a dinner out with friends in Tokyo. Rainbow kids were great, fast to respond and even accommodated a late date change when out plans were altered. Our babysitter Hyunseo was fantastic. We felt immediately at ease when we met her. We left her with three very weary kids between 10 and 3 yrs old and all of them had a great time. We will definitely use Rainbow Kids on our next trip to Tokyo.
