I've been wondering the same thing. Please tell me they are not gone forever.

too bad...because it helped me decide where to visit...stupid decision as far as I'm concerned...now I have to search other sites for interesting places to travel...it helped having a lovely desktop reminder to scan for destinations

I'm bummed about this too!

Thanks for your feedback on the new YDE email, Steven. We have recently discontinued the download feature. We know it will be missed, but we’re excited that the email now provides direct access to much more great content on the daily destination, including more photos. And in the coming months, you can expect more helpful resources right in the email itself. We’re still going to send out great escapes every day, and we hope you’ll be along for the ride!
