Just stayed at the Marriott Stelaris. We found it nice but very big and corporate like. Compared to some of the other hotels in Aruba, it is a bit plain and not like an island resort. For instance, the lobby in some of the other hotels opened directly to the pool deck with no door, whereas the Marriott's lobby has closed doors and lots of shops. The size is so big that you need to reserve a beach spot early in the day. Finally, while you can spend money at the adjacent Marriott time-share properties, you cannot use their pools.
We did find the restaurants to be very high quality, especially La Vista.More
