I think you definitely have the wrong idea with avoiding the party.
I ended up using retirement as an excuse to throw an all weekend party with 20 friends/couples down on the beach in Florida including a shuffleboard tournament, fishing charters, movie theater special screening of office space, custom iPhone app, and golf.
Pricetag was a bit steep, but the gang definitely enjoyed it. Still, I'm sure I'll get bored, and will need about half of them to help me launch a startup in another few years, so I figure it was worth it, and it was great using it as an excuse to get in touch with old contacts/friends.
