In 2 weeks, I'm visiting US for the second time. This time I'm traveling by car, through Houston, Austin, Dallas and New Orleans. I haven't been in any of these cities, and don't know how long I'll want to stay in each, so I hope to keep the itinerary as flexible as possible. Ideal would be booking the next hotel the evening before. My fears about this are:

1. Higher price. Would I get lower prices by booking through sites such as Hotels.com 2 weeks in advance, than calling the hotel the night before? Is that a fact, or am I tricked by the ads?

2. Lower availability. Can I be sure to get a relatively central hotel at this period, if I arrive with a short notice? I'm looking for 3-star hotels mostly.

In short, is it advisable to travel this way, if you're not ready to sleep in the car? :-)
