First, you must ensure that they do the usual "upgrade" to a slightly better room than you booked but with a connecting door (insist on it). Then you must wait for a couple with a baby to be checked-into the next room. Another few moments for the baby to start bawling and the parents to start making even more noises to quieten the baby down. Then you go down to the desk (don't call because the family next door can hear you complaining about them through the connecting door that is designed to improve communications with neighbors) and tell them you have a problem.

Watch the suite upgrade appear.

It works...

...typing from the biggest suite in Westin Park Central in Dallas to prove it.

It is that easy.
