He's a bounty hunter - as soon as he's got his money, he's off to catch another bounty and get more. Why the hell would he be hanging out at Jabba's in the first place?

Yeah, but since Jabba hated Solo so much, perhaps the bounty was large enough to take an extended leave. Maybe Fett's the type of guy who'd LOVE hanging out in Jabba's Xanadu for a long time. If I'm faced with the option of traveling space hunting men, or a nice cozy room sleeping with a backup singer in Jabba's Pleasure Island, I know what i'd take!
