It only took us about 15-20 minutes to get from Pop Century to the parking garage at Universal. It's then about a 10 minute walk to the parks, depending on where you are parked in the garage. I didn't think that was bad at all and there was very little traffic at around 8 AM.
Still, though, I think the Universal resorts are top notch and I would recommend staying there. It's such a treat having the hotels so close to the parks.
Suerob, when are you going on your trip?
