I'm going to be travelling cross-country very soon with two toddlers for the first time. I haven't had much time to plan this trip. The gear I will need will be two convertible car seats and two pack and play type cribs. My friend suggested I rent these at the destination. Has anyone done this? Can you tell me pros and cons? Is it easy to do? How does it work and are the items clean? I'm a germ freak, but I also want the easiest route for all things possible, so I'm really going to consider this since lugging my two car seats and two pack and plays through airports seems like a lot of hassle.
