Not if they've got any sense there won't be!
Large organisations (particularly ones that get many millions of visitors to their websites every day) never publish email addresses to the general public. To do so would be to invite attacks upon their systems via multiple emails. So you'll need to look for a web form to use as a means of contact. To do so you'll need to sign in first and then go via the 'Contact Us' link at the top of this page:

However there are plenty of things that you can do on TripAdvisor (such as notifying them that a place has permanently closed down) simply by looking for the relevant links after you've logged in.
