Once here, remove the UK map and copy the USA map from the CD, using the guest computer. Before you leave going back to the UK, put the UK map back on your unit for the drive home.
Another solution would be to buy a tomtom with SD card slot

prices of gps units are very reasonable these days
But on a serious note what pietu said above in post 15 will work, you dont need all the extra stuff like alg ect to get from a to b , and when you are back from holidays you can put the fully featured uk map back on
