If I remember correctly the skating rink and rock climbing were only open during certain times. The times were printed daily in the daily compass, which by the way had all the days activities listed for you. There were no age limits posted and I can not imagine there would be, My 7 yo has done rock climbing walls before. The mini golf was always open, I am pretty sure it was a help your self type of thing. We really enjoyed all the ammenities, however we found there was not nearly enough time in the day.
