Extra space in message

I have added the following code to my site wide message. But, for some reason, an extra space keeps appearing after “Conferences” no matter what I do. Can you tell me how to get rid of this extra space – it makes it look like there is a typo in my website copy. See https://beta.careyinstitute.org

<span style="color: #ffffff;">Host an event on our historic campus. ?Visit our <span style="text-decoration: underline;"><a style="color: #ffffff; text-decoration: underline;" href="https://meetings.careyinstitute.org">Meetings & Conferences</a></span> or <span style="text-decoration: underline;"><a style="color: #ffffff; text-decoration: underline;" href="https://weddings.careyinstitute.org">Weddings</a></span> website.</span>

Thanks!
