You might also consider allowing players to 'make your own bundle' concerning ships, the Oddy and Vesta packs are great ideas but how about allowing a 'cruiser/escort/sci' combo or something so you could get maybe a defiant, galaxy, sci Vesta for example. Players like to ability to customize their playing experience so rather than direct them into bundle packages allow them to assemble their own, to a degree. I'm positive I'd have bought at least one 'make my own' bundle if it were available.
When XP earnings during a Double-XP Weekend still feel like I'm underperforming,
there's something terribly wrong with the reward system...
