I am thinking of booking one, because Hotwire.com's price is DRAMATICALLY lower than online competition. However, their thing is you don't know exactly the specifications of the room you book. Any advice? I would end up saving about $500-1000 through hotwire!
I just booked one for April. I agree - I am saving about $700/person by booking via Hotwire. I went on the Dreams Punta Cana website (dreamspuntacana.com) and it looks like the "lowest" room they have is the Deluxe Room - which appears to be a standard hotel room. I plan to be by the pool/beach more than in the room anyway! I believe that it would have all the standard amenities. You could probably contact the resort directly and ask what there cheapest room is. The rooms probably have a view of the parking lot, but I can't imagine the rooms being awful.
I also heard a rumor that if you sign up for the iPrefer Card (http://www.iprefer.com/) - which is free to join - you receive a free room upgrade. I don't know if that is valid or not, but it doesn't hurt to try!
My only drawback was that you can't book ground transportation to/from the airport like you can with other travel websites like expedia, etc. Oh, well, guess I will have to cab it!
Enjoy! I know we are looking forward to our stay.
