We took our first cruise on Premier's Big Red Boat. It was a Disney tie-in...3 days at Disney's parks, including hotel, a rental car (which we had to drive from Orlando to the cruise port, park while on cruise and then drive back to Orlando. Airfare to and from Orlando was included. We pick it as a way to see if we would enjoy cruising.
You could choose which part to do first. We chose the cruise first, so if we hated it we could cling to each other and say, "Just a couple of days and we can have a real vacation."
Fortunately, we found we enjoyed cruising. Five years later we took what we called our first REAL cruise and we have gone at least once every year since.
This discussion really brought back lots of good memories.
