In fact, I wrote this post so that Stacey could cruise for free.
The Holland America and Princess cruise matches still appear to work note that the Holland America match offer is only valid for sailings until 12/31/23 and the Princess match is valid for sailings through 3/31/24 (but those dates might not be set in stone).
What’s new? The Carnival Fun Match is back and terms indicate that the program will be around until at least Decem(H/T to Chris in the comments).
