I find the beds to be really uncomfortable, and the furnishings are worn and dated. The parking is a pain if you have to use valet, and slow because you have to wait for them to unbury your car. The elevators are dark, dank, and reminiscent of a parking garage. There aren't enough elevators for the size of the property, so it's unlikely one will be located close to your room. My interactions with the staff haven't been terrible; they just seem indifferent. Housekeeping will often block the outdoor corridors with carts, and it becomes impossible to pass with a stroller or luggage.
There are just so many better options on Harbor, I always pass up DI&S unless I REALLY need a cheap suite.
