I booked one in New Orleans on 30 April but, unfortunately, decided to leave booking one in Miami 'until later'. When I booked a trip in Port Canaveral on 25 August, the majority of the Miami ones were sold out! I booked one in Belize a couple of weeks ago but very little is available. I'm travelling alone so hoping that there may be more available - especially for Miami - once we board but don't hold out much hope. Pat
