Two things I wish had been slightly different:
- Instead of just saying "I was saving it as a surprise one day" I'd rather Geordi said something like "I've been working on something for years now, any spare moment I can get. I was hoping to reveal it as a surprise on your 100th birthday... she's not quite ready, but she'll have to do..."
- Geordi saying that he'd been acquiring parts from multiple Galaxy-class ships as they were either retired or upgraded for the last 20 years. The Challenger, the Venture, the Magellan, the Syracuse, maybe the Galaxy herself (though I'd like to believe she's still in service somewhere and becomes the longest serving Galaxy-class ship in Starfleet history).
