I can tell you a lot about the Hemingway.. I've stayed a bunch. I have a friend that works the front desk that will give you as good a deal as possible. It's really a cool hotel to me. I stay there a couple nights and then the castillo or Sportsmens some too. It's an excellent location.
Give a call and ask for Victor at around 3pm-9pm their time. Tell him you're a friend of David in Atlanta and I referred you.

The rooms are not as nice as the Castillo or Sportsmens but it's suitable and the hotel actually has much more atmosphere than either of the two at times.. See if he'll get one of you a deal on Room 4 and the other a deal on room 15 upstairs if it's available at a good price. 4 or 15 will actually impress the chicas a little. If not 4 or 15 tell them to give you the best that's available otherwise- don't take 5 or 7. There's another room upstairs that has 5 beds in it and two of you could share because it's actually two rooms. I think that's room 16. You could ask him about that also unless that's too close for comfort.
Zebra's right about the environment but the staff is super friendly and honest and if you're bringing them after 9pm nobody is around and the front desk guys love to see your catch.
Their breakfast is actually pretty good and free- french bread, real butter, cheese, banana bread, eggs, rice and beans, pineapple, papaya, cantelope, native tamales, juices, coffee.
They have a large jacuzzi that I don't use.
You should be able to get a room with chicas included for about $42 plus tax.
