Datawarehouse Denormalization

Hi,I Have a table which I've de-normalized for my DimDestinationLocations. see Below[img]https://www.dropbox.com/s/le7958pr1yw37ew/DimLocations.jpg?dl=0[/img]How ever due to the amount of potential repeating rows I'm tempted toload out the distinct address's into another table and have a look up.For every booking there would be a Collection and Destination address, this table is going to get very large.Is there any room to do this in Kimball methodology or is it just bad practise.
