here are couple options..

1) Get (pay extra) a suite with more room at the end of a hall this should keep you further away from neighbors
2) Find a hotel with better insulation
3) Request to be switched to another room
4) ear plugs????

I feel its safe to assume you dont live in an Apt but a house and are use to the extra quiet space. In my opinion if you are going to travel that is one of the many things you need to sacrifice.
