We are going to HRH for 8/25 and switching to WL on 8/29 - 9/3. We did a similar trip two years ago, and found that while we like having our own transportation at Disney, we never used the car while we were at Universal. In fact, we were charged a daily parking fee at the Universal hotel, so it costs us quite a bit for a rental car we did not use for days. I need to make my rental car reservations now, but I am seriously thinking of using a car service to take us to the HRH, and then picking up a rental on 8/25 for the remainder of the stay. Has anyone done anything like this? Are their rental locations near Universal or Disney? There are five of us. If we are not going to save a good amount, I know it is not worth it. But 4 extra days of rental car costs (plus parking) may add up. Thanks for any input.
