Hi! I prefer the Gem, but having taken both ships out of NYC during school vacation season (I’m a teacher), I’d vote the larger ship, where there is more space for the kids to go. Last year we cruised during February and April vacation, and it felt packed on the Gem, while the Getaway just seemed like the kids mostly stayed up top with all the attractions.
if you’re not going during school vacation week, then I’d go 100% Gem, because I like the older ships. I did, however, really appreciate the waterfront and Spice h20 areas, especially during the school break week, to find some peace and quiet!
I hope you enjoy your cruise!
