The European cruises we have done (Norway, Baltic, Med) were not so much about seeing everything we could see, but about making travel fun and easy with a young child. It was so nice not to have to deal with moving hotels/packing/transport/etc. We always did some touring before the cruise, so we got a bit of that, but the cruise was just so, so simple. And my daughter had a blast. Plus, the cruises went to places we wouldn't normally get to go in one trip, like Estonia and then Russia or Monaco and Malta. Sure, you could visit those places in one trip, but it isn't simple to do that kind of itinerary without a lot more time for travel.
Which is why I'd love to do an Asian route. I'm not even too picky where. Hitting the theme park ports would be fantastic, but really, any itinerary over there would be something exciting and a great, easy, relatively hassle-free way to enjoy lots of different stops.
If/When they do start sailing from Ft. Lauderdale, I wonder if they will do the same old cruises or try something different. I think it's Princess that does some South American cruises from FtL? Anyway, maybe they will try something other than the standard fare! One can hope...
