You can book a prepaid reservation at Priceline (using their conventional booking tool, not their “Name Your Own Price” bidding system). This can also be found on Travelocity and American Express Travel without prepaying.
Prepaid bookings might have a better chance of being honored, but as with all these things there are no guarantees. I’m betting name changes and date changes certainly will not be allowed if the deal is honored at all. So choose a booking, get in on the offer if you wish, and then wait and see. Certainly don’t book other prepaid travel around this stay until it’s certain whether or not the deal is being honored.
