Delta was a wonderful hotel. We stayed on the 4 star side, and i'm not sure of the difference because it looked like the same front desk for both hotels. Because we were 3 people, they gave us an enormous corner room, which had floor to ceiling windows and probably the most amazing view of the Delta Dunarii. The only issue was the pull out couch-- it felt like nails were going into my back. I had to sleep on the couch itself which really isn't a bed. The wifi was a bit shotty-- always turning on and off, and not really available in the rooms. We had a couple of power surges during our stay as well but I guess that's because of the storm! The woman attending to the pool was kind of rude, and wouldn't turn on the pool lights for us, until an entire volleyball team entered the pool.
