I had planned to squeeze in a trip to the famous glow worm caves on a free day in Te Anau, but Tauck just notified us that Te Anau is now cancelled. Is it worth it to try to fit it in anywhere else or is it simply too far? They've added an extra day in Queenstown and in Auckland to make up for Te Anau, but I'm thinking that will be too far. I'd love to hear your thoughts from those of you who have been there. Thanks in advance!
