In farm hills owned by the Alexander family, they were treated to new night lighting and a market, a laser show and guest appearance by Smaug, the smoke-billowing, fire breathing dragon, thanks to Weta creative director Richard Taylor.
Hadlow said it was his fourth time back at the set, which seemed to grow in detail with every visit.
"Whether you're following the Lord of the Rings or Hobbit movies or not, if you come along here and have a look you will see that every aspect is done to the most fantastic level of craft and design. It's spooky, it's like being in the movie."
Cruise guest Linda Gravelee, of Alabama, was in awe of the set's authenticity after watching the movie in anticipation.
"It's awesome, it's one of the highlights of the whole cruise. To be greeted by all the Hobbiton people and everyone is so friendly."
Hobbiton general manager Russell Alexander was modest when asked about the continual development of the site and added extras, which now includes night lighting to accommodate night tours.
"There's lots of people, it's not just one person we're part of a team."
Although it was hard not to get excited when discussing last night's event, and Alexander could hardly contain his grin when he informed the Herald that it was Crystal's 20th world cruise and it was the only venue the company had visited three times. "This is the target market New Zealand wants and hopefully we're providing something to draw them in."
