When my daughter was 8 years old we took her to the opening of Planet Hollywood in Las Vegas to try and meet Luke Perry. She had a major crush at the time. She has cerebral palsy and uses a wheelchair, because of this the security guards (most were Air Force like us) moved her inside the gate, closer to the entrance, all the stars had to walk past her to enter the building. There was a woman dressed as Cleopatra who would ask dd who she wanted to meet and would position her self in such a way that they almost had to stop and say hi. Other times, security guards would guide the stars to dd saying "this young lady has been waiting all day to meet you"

They were all very nice. She met a lot of stars, the nicest -
Luke Perry (spent like 5 minutes talking to her, so sweet)
Paula Abdul (kissed her so many times dd had pink lipstick all over her face)
Eric Roberts (wrote the sweetest note in her autograph book)
Charlie Sheen (just funny and very nice)
Whoopie Goldberg (signed her Disney Lion King book)
Cameron Diaz (very sweet)
Steve Guttenberg (stood patiently by while Paula Abdul signed dd's book even though he didn't have to)
Bruce Willis and Demi Moore (very friendly and happy)
Rude (only two - most were very nice)
Maria Shriver (her husband Arnold had to practically force her to sign the book, looked very angry - Arnold was super though)
Sly Stallone
Another time we were at Planet Hollywood showing some family members the place and we saw Sinbad. He was leaving, surrounded by people but took the time to stop and say hi to dd. Posed for a picture and gave her an autograph. Very nice.
She also got to meet the members of 98 Degrees two years ago here in Oklahoma. They were really nice (not too hard on the eye either), spent a lot of time talking to her and posing for pictures and signing her CD.
I meet both Barry Manilow and John Travolta back in Phila when I was teenager. Both very nice also, although as I get older it seems that Barry keeps getting younger -- soon we'll be the same age.
Both dd and I are now big NASCAR fans, our newest goal - meet Jeff Gordon, Jimmie Johnson, Michael Waltrip and Ward Burton. We'll be at WDW next summer when they are at Daytona (Jul race), we just have to work on our plan.
