First of all, make sure that the car you select for your Fort Hood vacation will fit all your friends and your suitcases. When you’ve done that, think about where your travels will take you. If you’re planning to spend most of your time in downtown Killeen (which is just 3 miles away), book a smaller vehicle so you can squeeze into all the good parks easily. Is the open road calling you? Choose something with a little more room to move.
