If you're buying a Prius, you know you're sacrificing engine size and power for gas mileage. That said, the Prius V, with the tech package, is a great road trip car. The adaptive cruise control means that you can set the cruise control for 75 mph and not have to disengage/re-engage cruise control if vehicles ahead of you change speed. If you're going cross-country, the car can warn you of bad weather in the area. It handles really well on slick roads because of front-wheel drive. The one downside is that the built-in GPS is of fairly poor quality, but for longer trips, I use a stand-alone Garmin.
I previously had a Camry hybrid, and loved it except for the fact that the trunk was a joke. Since I tend to end up carrying a lot of stuff, I had decided that I would get a Prius V when it came time to replace the Camry. I've done so and it works great. The back seats are very flexible for either full sized people, or three dogs, or to carry stuff around. The mileage is very consistently in the low 40s. The cabin is comfortable, but significantly louder than the Camry was. The integration with the iPhone is great and I can listen to my stuff either wired or wirelessly. The pick-up is not zippy. You can floor it and it will get you merged, but it sounds like you are killing it. I generally drive gently, so not a big problem for me.
Gets you where you need to go, holds more than you think, and does so with great mileage!
