Need to de-activate one radio button in a question

Here's a weird one.

We have an event where the user is asked to choose one of two locations. One location is filled to capacity. What would be the best way to handle this? If I simply remove the option for the closed location, won't that cause the spreadsheet to shift data one column to the left? If that IS the case, can we do any thing that would prevent a person from selecting the closed location (other than simply adding text that that location should NOT be chosen?)

This question pertains to the form question "Please select the location that you would like to attend"

The selected  option submitted in a drop down will stay in the same field, which means that if you delete one of the options the already submitted data will stay there so your existing data should not be affected or altered. 

You cannot disable an option from the radio button and it can only be hidden with CSS code, if you would like to get this applied let us know which option you need to hide and we will be glad to provide the CSS code to achieve it. 

Also, we have a widget that you could use in the future, they allow you to select the available number of times an option can be selected and get automatically disabled once the number has been reached.
