Script to disconnect mapped drives and connect mapped maps

I need a script that will prompt the user for their location, then execute based on the user input.  Either choice will disconnect X, Y, and Z mapped drives and then map X, Y and Z based on their choice.  They will have two location choices to select from.  Based on their choice, the script will map the three drives based on UNC paths I provide to the script.  Feel free to include any additional intelligence into the script based on experience.  In the past, I have used a batch file for this but it has not done too well with consistently performing.  Sometimes it would not delete or not remap.  Sometimes it will say the drives were already in use, so I am preferring VB script since it can likely better handle things.  Thanks!
