Small update: (Will come back with photos later)

Mecure Korona - Budapest: 12 Euro at booking, 17 Euro at Hotel, but on check-in I was told Platinum can have the breakfast on weekends, the buffet style breakfast and eggs your way was larger than any hotel buffet I have seen before.

Mecure Zentrum - Wien: 20 Euro at booking, 25 Euro at Hotel, didn't take any, so many cafes near by with good food options for less, plus I am very full of sausage and wiener schnitzel.

Ibis Wenceslas Square - Praha: 20 Euro at booking, will know more tomorrow.
