We tend to book hotels on the basis of the breakfast being inclusive, which can mean a higher price. It much depends on where the hotel is located, if it's fairly isolated, then it's easier to have the breakfast there, if sited somewhere where there are plenty of cafes, if the cost of the breakfast separately equated to say £20, we'd probably be inclined to go to a nice cafe instead. I only ever have the fully cooked option when staying in a hotel, my preferred choice at home is Greek yogurt, fruit, sometimes porridge, not the whole bacon and eggs palaver. Last time in Europe we stayed in Seville, cafes aplenty, although the breakfast, as in most European hotels had a varied and plentiful choice on offer.
