I hope everything works out for SPACEWOMAN. Hope her group has a wonderful vacation !
That said .....I feel that Carnival has some screwy rules for good reason. Think about it...on most cruises 3000 PAX debark then another 3000 embark all in one day. On my 8 cruises I was most impressed with how proficiently these cruise ships are operated. They seem to know what they are doing.
Back home the roads are a muddle, the government is a muddle, even processing through an airport....a muddle. Carnival on the other hand can process 6000 pax in one day with comparably less muddle.
