It is possible to re-size any grid columns within Resort Hotel. To do so simply grab the grid line and drag it to the desired width.
You will notice that when you hover your mouse over a column header grid line, the 
mouse cursor appears. When this appears you can click and drag the column grid lines left or right to modify the column width.
See the following image.

•Right-click your mouse and select Reset column widths from the popup context menu or
•Hit the CTRL+R shortcut key or
•Select Tools->Reset grid column widths or
