They will mess up your reservation. I made two room reservations three months ago for a family vacation.  When I made the reservations I made one request:  I need the rooms on the same floor next to each other.  They said they will do it.  However when I checked in today, I found that they totally ignored my request.  I checked in as possible but they said they don't have rooms anymore.  They put us on different floor.  Now my wife and kids are going to be on different floor. What kind of idiots ignores one effing request.  Now my family needs to split up and stay on different floors. Way to f up someone's vacation. You f morons.
