We have been to Time Zone over a dozen times over the last 8 years, our son always seems to have a great time there. They offer numerous game packages and are great value, we normally just go for the $22 for 1 hour of game machines and 1 hour to do Dodgem cars, Laser tag and mini golf. You need to be careful when selecting a package as the unlimited game machine deals are only valid on certain machines which have a particular colour swiper and most of these machine are pretty basic, however if you like motor bike and driving games you'll love it as they are included (except a few). It's good value for an hours entertainment, however some of the games can seem a bit ordinary if your kids already have PS3 / Xbox and the like.
You get a certain number of goes on games which are "Ticket" games (you earn tickets for achieving certain goals / scores etc) and you can cash in at the end for a prize/s of your choice from the selection they have. It depends on how many tickets you've got as to what prize you can select, they do allow you to combine tickets from multiple card to get a bigger prize (2 separate player can combine their tickets) and you can hold onto the tickets for up to 12 months so you can accumulate the tickets and get a better prize. The prizes are a bit lame but the kids love to walk away with something at the end of then night.
