Hi we have a 9am Hobbiton tour booked on Dec 29th, 2018 and from what I've read it looks like Waitomo Glow worm caves are nearby. Has anyone done them both on the same day? We have an RV so we were hoping to do them both and then move on to our next destination. Or if it's too much should we do them on back to back days? Thanks for any help or suggestions!!
