Still not quite settled, I just found out the room we'd reserved at Sand Dollar has a terrible online review.
That is a disadvantage of SD: first time we got a unit one could call "sparsely" decorated, with plenty of room to hang and/or throw around gear etc. Second one had lots of "fishy" interior decoration and not enough room to walk around the bed without stabbing your toe... doesn't matter too much if you're out diving the whole day but still: you may get one you don't like.
PS I kind of doubt it anyone will mind if a Den Laman DFB customer takes a DFB cart to the Buddy side of Sand Dollar and dives off that staircase. The other side of Bari Reef is of course available to both DL and SD.
