Yes. I've been in a group that had 3 but that's before concierge booked them. This year we have about 20 people w/2 staterooms 00T. We got the double wide + the single next to it.
We traveled in January on the Wonder for my wife's 60th birthday with a total of 14 family members. My wife and I (and one son) stayed in concierge and were able to book two cabanas. We ended up not using them because the Wonder was unable to dock at Castaway Cay that day due to the seas.
