If I understand it correctly, the problem is that Priceline only guarantees double occupancy - it doesn't guarantee that you will get 2 beds. Therefore, if 2 beds is a must (as you say it is), then you can't use Priceline, and the only option is Hotwire. If you'd rather risk getting only one bed for a lower price, then you can try priceline, but they can't guarantee 2 beds. You need to choose which you want before thereuare can help you :)
