After going to Pattison's for my child's school party, we had such a great time that we've been back several times since. We've gone on Sunday afternoons and have found young kids and parents skating together. My 7 and 5 year old boys have a blast and they're not old enough to be embarrased to skate with their mom!
People use both regular skates and inline skates. It's about half and half. You can bring your own or rent. Some young children bring knee/elbow pads and helmets.
I wish they had more just regular skating and fewer special rounds. We end up sitting out a lot while we wait for the "all girls speed skate" or the "all boys speed skate." It's fun though.
