Putting this in the general forum since there may be more cancellations coming.
The Coronavirus FAQ for Rick Steves tour members webpage has been updated to include the following:
"As of March 11, Spain has closed all of its museums and national sites for a period of two weeks, and therefore we will also [in addition to the previously announced cancellations affecting tours to Italy] be cancelling our Spain tours that begin through March 27, 2020.
"Based on the new guidelines issued by the White House, we are reviewing our other tours for March and April and will be in direct contact with affected tour members in the coming days. We will have more information as the situation develops.
"If you are traveling on a Rick Steves tour with a start date through May 2020, and you are concerned about your travel, we can transfer you to a different 2020 tour or offer a credit for a 2021 tour. If you would like to transfer to another 2020 tour, please call Tour Sales and Service at 425-608-4217 to discuss your options. If you would like to cancel your tour and get a credit for 2021, please email us at email@example.com and we will process your transfer within 15 business days. We thank you in advance for your patience as our staff deals with an unprecedented volume of inquiries."
