Haha LOTR did it to me too! I went on a hunt of as many film locations as I could because of that. It was a lot of fun! Wait til I show you Hobbiton. It was one of the best days of my life! I took too many photos to reasonably organize though so that one might take a minute ;)
It was worth the extra money it ended up costing yes for sure haha, even the stress at the airport. I would definitely do it again :)
You have to plan a trip and go! You'll love it!
