Thanks for all your replies.
As egtravel mentioned, i really didnot mean playing with priceline. I thought i will not get the hotel for that price. I have used priceline a few times earlier but not for hotels.
Iam happy to pay the price i got. Only problem i have is the extra $50 the hotel is asking. Priceline does not tell anywhere that we are bidding for 2 people(atleast i did not see it). It told that only after price is accepted.

I will try the trick that few guys told i.e to check in with only 2 people. But only thing i want is a room with 2 beds.

Anyway thanks guys for all the replies.
