Not yet, we're hoping it won't come over for a while.

I understand your anxiety. I'm on the Best of England tour September 13th. A few points. I'm from Canada and if our government announces a travel advisory, I won't go. If a lot of the sights around England or London are closed, I'll reassess. I am a nurse and I know that the Corona virus is spread by contact. You can bet I will have my plane seat and surrounding area kept as clean as I can, but I'm not obsessing about it. In the meantime, I will continue to find great enjoyment in planning my trip, voraciously reading Rick's guide book, and anticipating a fabulous tour with great tour mates and perfect weather...a gal can dream:).

We're scheduled to go to London at the end of March and have not even considered cancelling. Of course, my husband is going to California first and then to Heathrow, so that might be a problem.
