The outlets are easy enough to get to from anywhere on idrive really, if you're willing to wait for the Trolly (we sell 7 and 14 day trolly tickets at murphys pub on idrive), or call a lyft or uber. Around that area you'll usually get a ride pretty quick. All the Rosen hotels are pretty good. The Rosen international is a pretty popular choice, and I've personally stayed at the one closest to Universal. There's also a holiday inn right across the street from icon park, which has plenty of resturants and some night life.
