Until our last trip it was always TL! But now, for a family trip, I'd say BB!
But I don't like the kid's area at TL. At BB it's all very central, you can always see the kids from your sun lounger when they're riding the slides. But at TL, they disappear out of sight and you have NO idea where they are, or if they're even still in the kid's area, so you have to stick with them at all times.
It's not an issue for me, as my DD was 13 months on our last trip and so I was with her all the time anyway. But my SIL has two older kids (5) who wanted to be able to have a bit of independence, but they didn't get it at all at TL!!
