I have an upcoming reservation at the Seattle airport Marriott. There was a message that a $2 fee per room per ride would be charged to the room each time the airport shuttle is used. This is the first time that I have experienced a fee for riding an airport shuttle. I hope this is not a new trend for 'revenue enhancement'. It is also unclear whether 'ride' implies it will be charged per room or per person. Will the rides back to the airport require cash payment or be added after checkout? Luckily, my stay is prior to this new fee, but I would like to learn if this is a property specific situation or growing trend.
