Took the car into Honda Leesburg (MUCH better customer service than the one in Fairfax) for a major tuneup last week and needed to kill about two hours while they serviced the car. Had the 4-year-old with me, so decided to have their shuttle drop us off at Dulles Town Center, where she could play and eat in that amount of time. The Honda guys must have been ripping through their work, because we got the call that the car was done in an hour and 45 minutes, barely enough time for her to take in the entertainment and get something to eat.
Since the mall had just opened, we started with the Jet Blue toddler play area, which can get super-crowded during the day. Loved the foam slides and tunnels in the shape of an airplane, control tower and truck, and loved the benches surrounding the entire area to keep the kids penned in. Some things to note: there is a maximum height requirement, I think it was 42 inches; and it closes daily at 1:45 p.m., probably so they can clean up for an hour or so.
Next, she took a ride on the carousel; it was $1.50 a ride, but parents can stand for free. That was good for about, 2 minutes, then it was downstairs to the train, which was a better deal: $1 a ride or you could get a 12-punch pass for $10. Parents had to pay to ride, though.
All in all, it was a great way to while away the time. If we had more of it, I would have liked to have eaten at The Cheesecake Factory, but we had to grab a quick meal at the food court instead.
