There is one level at DQ with things like skee ball, puck bowling, and other video type games that dispense tickets. These game cost $$$. You purchase a card from one of the CMs. I think we gave her a $20 and we got a card with 50 game credits. Cards range from $5 to whatever you want to spend. The tickets from the games can be redeemed for the typically cheap carney type prizes. The boys actually did well and got enough tickets to get their mom a Disney Quest t-shirt. So $20 for a t-shirt and the fun of playing all those games, not bad.
In general, DQ was a blast. The virtual reality games were fun, and the time warp to the old games where you could play Space Invaders, Joust, and other classics made it worth the entry. We went twice during our 9 day stay, using "plusses" (we had 5 plusses to use). Didn't stay too long either time. Both times were ~ 7pm in the evening. not too crowded either time. DW is not a HUGE video game fan, so after doing some of the family things and te obligitory game of skee ball, she took a stroll through DTD. WHen she returned, we headed back for the hotel.
