I just went to look at my planned summer trip and I had no issue looking at it and then sending it to my email. You might want to try again. It looks as if they are shutting it down and don't have a replacement queued up-- poor planning
..............from their FAQ's
Good Sam Club is working on an improved version of the trip planner. When will the new version be available?
The current trip planner will no longer be available, effective April 10. Our goal is to launch the new version of the trip planner by the end of 2019.
