Have been on both and my husband and I prefer the Jewel. We do not need the fun things like the race track.
Loved that the games did not take place in the atrium freeing up that space as it is always crowded on the larger ships.
Loved the three elevator banks instead of the two which made all the elevators not crowded.
Loved that you did not have to make any show reservations--you just showed up.
Loved that even sailing on a smaller ship that was full, it never seemed crowded in any area.
Now, if it had a Vibe, it definitely would be my favorite ship.
