No Carnival will close your booking if you miss a last payment date for sure. Now they stated room assignments would happen by the 21st of November it's now 6:30am on November 22nd and both my room are still TBA. Can Carnival please get their act together. Room where originally picked mid ship balcony deck 8 next to each other, waiting to see where i end up. My be a nicer ship but this blows waiting on them. PVP asked me to wait untill rooms assigned before calling.
