The other cool thing was that they set up one end of the rink with roller racers/flying turtles for kids (um...and adults ;) lol). That's great for kids that had enough of the skating or are too small to skate.
During the party, they also had some costumed character come out to play games with the kid and to take pictures with the birthday girl.
A private party is a little pricey at $299.99...but might be more manageable if you had a combined party for your kids as they could invite everyone they know practically! You can also have a party during public skating hours...this is $13-15 per person.
I'm toying with the idea of combining my son's and daughter's party next year and having it here...we'll see!
