Ultra-luxury Crystal Cruises has come up with a great way of entertaining customers aboard. 

Master Magician Rich Bloch, will organize the shows with magicians from Hollywood's renowned private magicians' club, the Magic Castle.

The incredibly intimate evening shows have added yet another live entertainment option to 13 luxury European cruises this year, and every voyage in 2013.

The new affiliation, aimed at mystifying guests of all ages, offers complimentary classes for adults to develop their own magical acts, educational enrichment on subjects like Houdini, and children's shows on select summer and holiday sailing.

That's not all. There will also be access to the secret Castle itself when in Los Angeles.

"Considering club guests can only gain entrance if they're in LA and invited by a member, Crystal's Magic Castle at Sea provides rare access to a truly spellbinding entertainment experience," Crystal's Vice President of Entertainment, Bret Bullock said. "We're thrilled to offer our guests yet another unique choice in high-caliber vacation fun."

Entry at the Secret Castle is only via invitation or tickets that have to be availed on a prior notice. Guests can choose from multiple, half-hour performances over the course of several nights. 

On the night of the show, customers would be taken to a special entrance to find the ship's Pulse or Luxe lounge transformed into the mysterious spirit of the Victorian-era Castle, with flameless candles, lighting, music, murals, bookshelves and magic movies from the 1920's. 

With attendance limited to just 25, audience members are privy to an extremely up-close look at sleight-of-hand tricks, impossible feats, and bewitching hocus pocus. 

Once the show is over, the customer has to retain the ticket for the next night.

Crystal's European season includes Baltic and Northern European cruises until September and Mediterranean sailings until December. One can choose from 7-12 or 5-8 days trips on the CrystalCruises website.
