honey737. All my trips are great, of course! I'm not going to start (or get involved with) a petty argument about whether cabin crew or flight deck are more likely to spoil a trip; it would be invidious and ridiculous.
Each trip has its own pleasures. Some, for reasons of fatigue, time zone changes, lack of ground time, local customs, or whatever, are unlikely to ever be 'party' trips. That's part of the job. Sometimes it's just nice to get your head down for 12 hours!
