Putting a URL in the Location field of a Google Calendar appointment is not a good idea. Google tries to treat it as an address and attempts to draw a map. The URL is not clickable by recipients and causes frustration. If there is no Location, the URL should be placed in the Description instead.

@webmink Thanks for the comment. I've tested this in Google calendar on my mac and the app on my iphone, and I don't see this happening. The link remains clickable and it doesn't try to generate a location preview unless I click on the "Preview in Maps" button, though it fails somewhat gracefully with a "No results found". Having said that, I just noticed if adding the event via mobile (iPhone - Safari or Chrome) the url is not included as a location - it's getting stripped out, somewhat aligning with what you're saying. Either way it seems we need to also include it in the description instead for Google Calendar (the other calendar formats seem to already include it).
