More good reporting from your friend Chris Owen, who has a story in Cruise Critic highlighting increased security measures at the Mazatlan Port, including the security wall, vetted tour buses, and fun things to do for passengers staying in the port area.  It's based on an interview with Alfonso Gil during Chris' visit for Fiesta Amigos. Here are a few excerpts:

"There's already been movement back. Princess Cruises was the first to announce a return with, Sapphire Princess, which is scheduled for six sailings through April 2013 (Star Princess and Grand Princess will also be calling.)"

"Firmly believing the destination is safe and eager to see more ships return, the Mazatlan Port Authority recently allowed Cruise Critic complete access to the port and surrounding areas. "We have nothing to hide here," said port director Alfonso Gil, adding, "Our port is the safest of any in Mexico and safer than many in the Caribbean."

" . . . .cruise travelers venturing out in Mazatlan will discover the region's natural beauty, great beaches and internationally acclaimed attractions. An in-place tour operation stands ready for cruise ships to return with a variety of offerings, including surfing lessons, horseback riding through a Mexican rainforest, a tour of a tequila distillery and a visit to the original Senor Frogs. Excursions are priced to offer value -- like a $35-per-person day pass to an all-inclusive hotel, including transportation there and back, all-you-can-drink-and-eat plus unlimited use of the beachfront facilities including golf." 

Many congratulations!
