In addition to what Tink-n-Belle said...
Curiously, my son said one negative on this last cruise was that they had "open house" at some point every day during the cruise - usually that's just a few hours on the first day. It stunk for the teens, b/c most activities were shut down during that time, and parents and kids of any age were allowed to come in an check out the Vibe (but, as I said, most stuff was shut down, so there wasn't much for anyone to do but tour it). Hopefully
DCL will get enough feedback on that to cut it down.
