I just checked out the 4pts for the DUS DO IV. I had a lovely stay and definitly thought it was worth the points to do an award stay. It was only 12,000 points for four nights. Several people at DUS DO IV paid to stay and got rates for less than 80 Euro a night.
My room had excellent wireless capability. Breakfast was included which was quite extenisive. Cold cereals, yogurt, breads, scrambled eggs, streaky "American" bacon, hard boiled eggs, cheeses, tomatoes, cucumbers, coffee, tea, juices, and bottled still water. The breakfast staff were very polite.
I made several 800# calls and was not charged an access fee. There is no restaurant for afternoon/evening meals but they do have a small bar area which sells beers, mixed drinks and coffee.
The desk closes sometime in the evening so if you are going to have a late arrival (past midnight) you may want to call and see what the procedure is for checking in late at night.
The room had a hot kettle, and mini bar fridge. Drinks inside the fridge are complimentary (don't get too excited). There were 4 drinks. 1 sparkling water, 1 Coca-Cola, 1 grapefruit juice and something else that I don't recall. Items consumed each day were replaced. There was also room for other items in the fridge.
If you turn right outside the hotel there is a small convenience store on the corner that sells alcohol, candy, and bottled still water at fairly reasonable prices.
the room was not huge but it was designed with efficiency in mind. I had adequate storage for my items and didn't feel like I was tripping over myself. The room was very spacious for a European 4 points.
I am a platinum but didn't receive an upgrade. I did check out a few other people's room and they all seemed adequate.
