I am not sure how much time we would be spending in the room, so my focus had been more on the location. The difference in price between the rooms per night is fairly steep, with £370 for Conrad versus £646 for a king deluxe room at Park Lane. In your opinion, would the view at the latter be worth the difference in rates? That increase in room rate would be a bit of a stretch on the vacation budget, but it is doable.
