I wouldn't normally recommend this hotel, but you can get a room for $57.50 right now at the Crown Plaza Corobici (formery a Sol Melia hotel the Tryp Corobici). If you have one special novia or don't bring girls back to your room, this is a very good deal.
The plusses:
The remodel was recently completed.
Good price. The $57.50 includes tax (you'll actually use points)
Has a pool.
You reportedly have access to the free hotel shuttle
The negatives:
Not centrally located, it's on the edge of downtown next to Sabana Park.
They have a good buffet breakfast but reportedly it's not available with this promotion.
REPORTEDLY THERE IS A $50 CHICA FEE!

To get this rate (rooms are usually over $100 a night) you'll need to use priority club points. You can purchase points for $11.50 per 1,000 points. It would normally take 20,000 points to redeem at this hotel, but right now this hotel is a "pointbreak" hotel and you'll only need 5,000 per night.
This deal is available for bookings until the end of August.
