Today’s invention is a SeatGuru for hotel rooms.
Since most ‘cheap’ hotel chains have internal layouts that are almost identical, when booking a room, it would help determine the relative noisiness of different room numbers.
These data could be based on crowdsourced feedback, from previous guests, as well as a model which would include the (weighted) effects of eg proximity to the lift, firedoor, ice machine, family rooms, kitchen etc.
This invention was inspired by a conversation my wife had with discerning traveller Steve Cook.
