HONOLULU - More than a week into his Hawaiian holiday, President Barack Obama is proving to be a creature of habit.

While some travelers seek adventure and spontaneity, Obama seeks comfort and consistency. His routine here in Oahu, the island where he was born and mostly raised, is by now patently familiar to the locals trying to catch a glimpse of their hometown president, and the reporters who come here to cover him.

Obama is almost certain to spend his mornings working out at Marine Corps Base Hawaii. A leisurely dinner with friends and family at Alan Wong's Restaurant, an award-winning eatery in the neighborhood where Obama grew up, is now an annual tradition. And a guaranteed place to spot the president is at Island Snow, a shop near his rented oceanfront home, where he treats daughters Malia and Sasha to shave ice, the Hawaiian version of the snow cone.

So, doesn't the president ever want to mix things up a bit, maybe go somewhere new? Not really, says White House spokesman Bill Burton, who is with the president in Hawaii.

"Like most Americans, the president knows what he likes in his own hometown," Burton said. "He's been going to a lot of these places since he was a very young child and they hold an important place in his life."

Of course, things have changed since the days when Obama lived here with his grandparents and scooped ice cream at a local Baskin Robbins. The logistics of any presidential movement make a truly spontaneous stop nearly impossible. Advance teams scope out all potential destinations ahead of Obama's arrival, and Secret Service agents have to sign off on security.

That means no more walks in the park or swimming at public beaches. The Obamas now spend their beach time at Pyramid Rock, a secluded spot on the marine base, and snorkel only at Hanauma Bay on Tuesdays, when the nature preserve is closed to the public. There are also no more rounds of golf at Olomana, a course next to a busy highway where Obama played as senator. He instead opts to play at the course on base or at the more secluded Mid Pacific Country Club.

Another familiar element of Obama's Hawaiian vacations is the small circle of friends and family he surrounds himself with while he's here. His sister, Maya Soetoro-Ng, lives on Oahu with her family. Marty Nesbitt and Eric Whitaker, two of Obama's friends from Chicago join him here for the holidays, as do childhood friends Mike Ramos and Bobby Titcomb.

Titcomb's house on Oahu's North Shore has also become a regular stop for the president. Obama attended a barbecue there Thursday, with his 20-car motorcade making the hourlong trip across the length of the island.

While Obama's trips here still generate excitement, some local residents would like to see the president more engaged with the community.

"Just because we're in Hawaii and it's paradise doesn't mean it's paradise for everyone," said Mike Irvine, who has lived in Honolulu since 1985. "Going to a black church, or maybe a homeless shelter would be a big deal."
