Trying to help out with a room recommendation:
If you want something at the Dolphin, close to the pools, close to Picabu, and close to the bus stop, we just stayed in 1169, and we loved it. The bathroom situation is a little tight, but perhaps it's the same in all of the Dolphin rooms. At Swan, the bathroom was much more spacious - two sinks - ine INSIDE the bathroom, one outside. In 1169 at Dolphin, there was only one sink area, outside of the bathroom. The bathroom only had a toilet and a shower stall, and it was pretty tight, but OK.
So, this room was down a short hallway between Picabu and the fitness room. We had a sliding door that opened to a table and chairs that was a few steps from the walkway between the pond with the swan boats, and the hotel. So, we faced the Swan boats, and could walk right out of the room to the walkway to the pool, but also, there was a short path right next to the basketball court that led right up to the bus stop. So if we were hitting the pool, we could just step outside of the sliding door, but if we were hitting the bust stop, we could walk down the hallway, and exit the door next to the fitness room. I'd say there were probably about 10 rooms down this hallway. I think someone posted a pic in this thread, in a very nearby room. I will as well a lil later.
