Just read about the massive demonstrations planned from June12-14...the exact 3 days we will be there. Too late to change all of our reservations and all of our pre-booked tours and attraction tickets so how bad is it going to be? Will the streets all be closed off? Will places like Westminister just close? I live in a small town and just navigating a city on a normal day is a challenge for me! Any advice (except stay home) and information for a concerned traveler would be appreciated.
