"Gosh, if you were a Royals fan growing up and it's freezing in Kansas City and you could become teammates and friends with guys like Joe Randa, Jermaine Dye, George Brett and Jeff Montgomery, it'd be a no-brainer," Sweeney said.
Sweeney and Dye are first-time participants in the camp, and other former players committed, in addition to Brett, Randa and Montgomery, are Frank White, Willie Wilson, Dennis Leonard, John Mayberry and John Wathan. Several others are expected to be in the camp as well.
The camp participants receive two personalized uniforms, are coached by the former Royals and play two games a day, including one against the alumni.
The cost is $3,900, and full payment is required by Nov. 30. Participants must be at least 30 years old and be in good health. As an added bonus, campers will have the opportunity to purchase tickets for the 2012 All-Star Game at Kauffman Stadium and other associated events, camp coordinator Dina Blevins said.
Applications can be obtained by calling 816-504-4150 or by visiting www.royals.com/fantasycamp.
"If my wife gave me a Christmas present to go and hang out in Arizona where it's beautiful and share a locker with George Brett and these guys, it would be a great gift," Sweeney said.
"Just to be a part of this exciting time in Royals history -- we've got the All-Star Game coming this summer, and you've got the brightest crop of young stars in all of baseball wearing Royal blue. Just to be part of it as a fan or a player is something special."
Sweeney, who retired as a player prior to the 2011 season and joined general manager Dayton Moore's staff, recently helped out at the instructional league in Arizona. He plans to become more active this year, coming into Kansas City and visiting Minor League teams to help coach players.
"We're still trying to identify the exact role, but that's what Dayton and I have been thinking about," Sweeney said.
Sweeney also will be in the Royals' Spring Training camp, but before that comes the Alumni Fantasy Camp, and he's pumped.
"George and Joe [Randa] and guys like Monty have said, 'It's a blast. You come out there, meet these guys, and by the end of the camp, you're slapping each other on the back and it's like you've known each other all your lives,'" he said.
